Trinity: Hello and welcome everyone to another episode of Waiting to Be Signed, a very special interview episode this week. We're joined today by Marcelo Soria-Rodriguez and Andreas Rau, who both collaborated on the project Toccata recently, a project we've talked a lot about on the show, on Discord, and on Twitter. Everyone really loved it. Continue to love it.

Will: Everyone continues to love it, which is why we're so pleased to have them on the show today to talk more about that process. Marcelo, Andreas, thank you so much for joining us.

Marcelo Soria-Rodriguez: Thank you for having us.

Will: A special thanks to Andreas too for coming straight from the hospital to here. Much appreciated. Congrats on the birth and joining the daughter crew — very exciting.

Trinity: That's also extreme dedication to your craft, coming here to talk about it right after. We could have pushed this, but we appreciate you coming.

Will: It's really exciting for us too — we've never done an interview like this, timed so closely to a release. I'd assume most listeners are at least familiar with your work on fx(hash), but perhaps each of you could give a brief intro of your background in art — and in this case, music — and how you came to be NFT artists or generative artists releasing on Tezos and fx(hash).

Marcelo Soria-Rodriguez: Andreas, go ahead.

Andreas Rau: Sure. I'm Andreas. I'm a generative artist, as most of you probably know, but I'm also a jazz musician — that's something fewer people from the Twitter sphere know about. That's actually where my creative journey began: music. Jazz came later, but everything is built on that foundation. I'm from a musical family, so I started playing piano really early on. The visual side came in with my studies — I studied design and worked as an interaction designer for a while, always pursuing generative experiments on the side, using generative systems in my design work and creating generative artworks. I did a lot of digital and physical work — installations, kinetic pieces, things that move and behave when people move through a room.

When I first heard about Hic Et Nunc, Tezos, and NFTs, I got really interested in this new mechanism for distributing artwork to a broader audience worldwide. That caught me immediately. It was fascinating to see how people were engaging with this new medium, how active the Tezos art scene was in the early days of Hic Et Nunc. That's where my journey into crypto started — I read a lot about NFTs and about the technology, as far as I could wrap my mind around it.

Then I decided, very deliberately, to mint my first NFT on Tezos and Hic Et Nunc. Partly because I wanted to go with a proof-of-stake blockchain — Tezos had been such a nice alternative to Ethereum for so long, with a much lower environmental cost. But the community was the real reason I started minting and actively participating in that whole sphere. There was one event that was the turning point for me: the Creative Coding Meetup in Berlin, around March or April last year. Talking to Raphael and the others there — everyone was talking about NFTs at the time — that's really where I started investigating and putting time into figuring out what I could do with it.

Trinity: Were you part of any online communities before that? A lot of the people we've talked to were active on Instagram or Twitter, sharing works in progress. Was that a sphere you operated in, or was it purely the Berlin meetup that pulled you in?

Andreas Rau: It was more the latter. I'd never really been active on social media — I literally created my Twitter account when I minted my first NFT, figuring if you want to engage with a crowd, you need one. Before that, it was very much focused on interpersonal relationships from those creative coding meetups in Berlin, and with a couple of people around Oslo, where I live now. That was my community before I joined Hic Et Nunc.

Will: Marcelo, your intro?

Marcelo Soria-Rodriguez: I'm Marcelo, currently a generative artist. My creative endeavors have been in the back of my mind for as long as I can remember — as a kid I wanted to be an architect or a car designer. Somehow I ended up an engineer by training. Along the way I always had an interest in photography and music. I actually started music before anything else, though I never had formal training and didn't dedicate enough time to learn it properly — I play piano a little, simple things, and I like composing my own little pieces.

I took up photography, then digital art experiments — 3D stuff, ray tracing, a long time ago. As I studied engineering and computer programming, I started experimenting with code using MATLAB, the software I used for my engineering work, and that led into image processing, which really attracted me. I ended up working in data analysis for a large financial multinational. At some point it became clear I wanted to dedicate more time to these things. I quit my job at the bank and tried to set up my own consultancy — really more of an excuse to find a proper outlet for certain projects of my own.

Then the lockdown came, COVID came, and trying to sell consultancy services to other companies didn't make much sense when everything was frozen. So I started dedicating more time to coding at night, and that's when I built my first large generative system, which became Entretiempos, my release on Art Blocks. I didn't set out to become a full-time artist — I liked doing this, but I didn't really let myself think "I might be an artist." By the end of 2020 I learned about NFTs. I'd been in touch with blockchain for a long time, but I didn't realize this was, again, this new way of distributing content. I got interested, read for months while totally lost trying to understand the terminology and jargon, and eventually decided to try my luck and share my work too.

Entretiempos — Marcelo Soria-Rodríguez

My first NFT was released on OpenSea in January 2021. I still didn't know about Tezos, but a few days after Hic Et Nunc launched, I discovered it and just stayed — the art was amazing, the community was amazing, the feeling was phenomenal. That's where I've spent most of my time since.

Will: We love having both of you here dropping on fx(hash) — it's always a big moment whenever either of you releases, which is a nice segue into the collaboration, which was extremely exciting for everyone. Can you share how you came together? Were you aware of each other's interests and background in music, and is that what caused you to pair up, or was that a happy discovery once you started collaborating? How did you begin to conceptualize Toccata?

Marcelo Soria-Rodriguez: Andreas, you want to start?

Andreas Rau: It's clearly based around this whole idea of music. I remember — I think this is true — that I was the one who first reached out to you, Marcelo. I'd been fascinated with his work for quite a while. What always speaks to me in Marcelo's pieces is how musical they are, even though they're visual — that touches me very much. As I said, I'm a jazz musician, making music on a regular basis, and I really wanted to find a way of incorporating that practice into my visual arts practice, into my NFT practice. That's why I thought it would be really nice to do something together with Marcelo — to walk this musical journey together. That's where it all started.

Marcelo Soria-Rodriguez: He did get in touch with me. I'd already been contacted by fx(hash) about doing one of these collaborations, and I wasn't sure about it — my calendar wasn't clear, and I understood the pieces would need to be ready within the first month or two of the fx(hash) 1.0 release, which would have been impossible for me. But then Andreas reached out, and I thought, of course — I'd been following his work and had been a fan since I discovered it. I thought if anyone, this could be a great collaboration, and I was very interested in exploring what a collaboration even means, because I wasn't sure how to approach that.

It was a fantastic discovery to learn he was a musician — I didn't know that. Music came up very quickly; he mentioned that my pieces had some kind of musical rhythm or reference to them, which honored and humbled me, because music is very important to me, even though in a lot of my pieces I'm not consciously looking for a connection to music when I do the visuals. Somehow it conditions everything I do anyway. So hearing that from him was special. Very early in the conversation we landed on musicality flowing through both our artistic interests, and thought maybe we could actually bring music into the piece itself.

Entretiempos — Marcelo Soria-Rodríguez

Trinity: How did the collaboration continue from there? There's so little insight into how these processes actually work — we've talked to others who've done collaborations, but it's a real treat to have both of you here together. Once you land on this initial idea — we want to do something in the sphere of music — what happens next? How does it progress from that initial spark into something full and final that everyone ends up loving?

Andreas Rau: If only we would know. It's really interesting how everything just went organically. I've done collaborations before, but never online collaborations in that sense — Marcelo and I have never met in person, which I also find remarkable. When we first started talking, we quickly found a shared interest in music, obviously, but also in this idea of things that evolve over time, that change in ways you'd never guess they could. And it was also the time when the war in Ukraine had just broken out, so it was very much a period of change — things we'd taken for granted for years were suddenly not so given anymore. That became the other main topic we agreed on quickly, because both of us were really interested in exploring that and bringing what was happening in Europe into the piece. Do you have anything to add, Marcelo?

Marcelo Soria-Rodriguez: Just that I'd stress the point about things growing organically. These were just conversations, sessions to get to know a bit more about each other's artistic mind in the moment — we didn't really spend time getting to know each other on a personal level back then. It was very much focused on the art, trying to get a feeling for what we each had in mind and how we could eventually find something to build the collaboration around: taking from the music, taking from this interest in decay, in degradation, in cycles, stemming from the news about Ukraine.

All of that happened in conversations that had no real direction, and I think that was actually good, because we never stressed about saying "let's take this style of yours and this thing of mine and see what we can do." It was more a question of finding the common ground we'd both like to explore, and figuring out how to make a real collaboration rather than just a cut-up of pieces we already had lying around — which is what it might have become otherwise. Maybe because of the situation in Europe, it called for something different. I'm not saying that's necessarily the whole story, but that was in the air, at least floating around in my mind.

Looking back, I think it was so important to let things mature, to let those conversations take their time. We skipped deadlines for weeks — we'd agree, "I'll try to do this thing," talk again next week, and: "I didn't get the chance to advance on this." I was a complete disaster throughout, honestly, because I had other things going on, other things I had to look into, and new ideas that came along that I tried to squeeze in. But looking back, I think all of that was very good. If I'd had a completely clear table, I think I would have rushed the search for the concept. In my experience, the result is always so much better when you let things rest for a while. Don't you think, Andreas? I really did want to work — I'm not saying I left things intentionally — but I think it was good to leave some of those ideas hanging around and see what happened to them after a week or two. And since you're busy with other things in the meantime, those other things feed little ideas back into the general thought that eventually brings you to whatever you end up doing.

Andreas Rau: I 100% agree. It was so fruitful that both of us had different things going on at the same time. What Marcelo just said is only half the truth, honestly — because even when he'd come back a week later and say "I didn't get to work on this," he'd actually have worked on a ton of other things: "We could do this and that as well, I tried this here." That's kind of how we progressed — we both experimented constantly, organically, taking our time to find out where we actually wanted to take this. There was no real goal, no vision in mind when we started. There was just a path we wanted to walk together, figuring things out along the way. Taking our time — that's something I really appreciate, both about this collaboration and in general in life. Letting things sit and ripen makes everything so much better.

Entretiempos — Marcelo Soria-Rodríguez

Trinity: It sounds like the initial concept around music came together almost immediately. But Toccata is incredibly complex and rich, and clearly took a lot of time to mature. At what point did you decide on the form you were pushing toward, and what was that like?

Andreas Rau: Hard to say, because there was no clear cut. I'd say the basic concepts of the piece — conceptually, visually, and musically — we settled on rather quickly. This idea of shapes consisting of a multitude of shapes, shapes that move, contract, expand, evolve over time — that base concept was there almost from the beginning. Then we just built on it. Instead of trying to nail down the exact shape, the exact colors, the exact behavior up front, it was more: this is the base, let's see what we can do from here. Let's find out how these shapes actually behave, what kind of simple geometric shapes we can use, or whether it should be more complex — should it be noise, should everything float, whatever. Where the visual idea itself came from, I couldn't tell you, but it arrived very quickly too. We established our understanding of the "holes," as we used to call them, almost immediately and just kept working with them.

Marcelo Soria-Rodriguez: We had a Figma board that Andreas set up to share ideas. We started putting concepts there — and the truth is, like Andreas said, there weren't that many concepts. It arrived very quickly and went up on the board. Then we played around with that concept for a long time — first in two dimensions, completely flat geometry. Then we thought, what if we expand this into 3D? That would give us some extra behavior for free once we settled on a projection perspective.

So there was an exploration of the visuals — what shapes, what behaviors, as Andreas mentioned — and at the same time a path of technical exploration. I hadn't done any relevant 3D work before, so I had to learn how p5 works in 3D, and I was a little lost initially. For quite some time it was really about the concept — the holes, which seemed like they could form interesting things when combined in various ways — but figuring out how to create them in 3D, and reasonably efficiently, even though the piece still isn't the most efficient one out there. I'm sure there are more performant ways to do it technically, but what we got was the result of that path.

You asked when it clicked — it's hard to pinpoint, but I think it had to do with once the technical side was solid enough to run on most computers, then playing around with it until it clicked emotionally. At least that's what happened for me: the first time I looked at it and thought, "Wait, this makes me feel something" — I got an emotional reaction from the piece — I knew we were onto something. After that it was just a matter of playing around with it more until it really made you feel it. And toward that emotional goal, music was absolutely key.

Will: I think for both of us co-hosts, it was that combination of the music with the flowing, rhythmic motion of the holes—

Entretiempos — Marcelo Soria-Rodríguez

Trinity: And the decay.

Will: —and the decay that drew us into the piece. It's phenomenal hearing the story, how organically it came together, neither of you working from pre-made or half-made projects — because where you arrived is so unique for fx(hash) in particular. This is an fx(hash) show: very often pieces are static, two-dimensional. To make something animated, 3D, with a music element, is almost like setting yourself up to fail, given how the community tends to react to projects like that. A lot of animated or 3D work just doesn't get collected at the same level. So it feels like such a breakthrough to have Toccata come out and resonate the way it has — that emotional pull, primed by the music and the animation together. I don't know if there's a real question in there — it's kind of amazing it worked out like that.

But I would love to know more about the music itself. There are eight different variations across the piece's properties — in some of them I can hear individual phrases that seem reinterpreted from the Toccata you referenced as a musical influence. Can you talk about how those variations were composed, and where the generativeness lives in the music and the decay — how the sound side actually works?

Marcelo Soria-Rodriguez: We discussed many concepts, and this isn't a linear story of how we got there — it was more a combination of ideas and feelings, then technical exploration, and then, once we had built our tools, figuring out what we could actually do with them and where they could take us.

We'd both independently loved the idea of recomposing works, and there was also this concept of the decay of a musical piece. What does it mean for a piece to decay? Is it audio distortion? Notes sounding offbeat, or off pitch, or missing entirely? Music carries such strong emotional weight — it's one of the best ways to encode emotion — and your relationship to how a piece develops is emotional too. That's why Toccata by Prokofiev became such a beautiful reference, brought in early on by Andreas. We wondered whether we should make variations on it, record it, distort it — how would we translate this piece into the work?

We didn't want to build our own entire sequencer inside the piece. In the end, that's exactly what we did — we have a full-blown sequencer and composing tool in there, among other things. It started from a simple question: how do we technically add music to the piece? We explored p5.sound first, but it was buggy. Then Andreas tried Tone.js, and it worked much better, so we built on that foundation. Should we use synthesized sounds? Prerecorded segments combined as audio files? It kept evolving, in a constant dialogue between the technical possibilities, our time constraints, and the—

Entretiempos — Marcelo Soria-Rodríguez

Andreas Rau: The—

Marcelo Soria-Rodriguez: artistic direction we wanted the piece to have. Through that dialogue we'd discover what was possible with the tools we had at each stage — "with this basic sequencing system, we can do this" — and then Andreas would add more capabilities, which opened up something else. That's the general arc of it, but Andreas should talk about the details and the generative aspects, because they're fascinating.

Andreas Rau: As Marcelo said, the basic idea was: let's not just create a generic generative-music sequencer. As a musician, I've always found it tricky to really connect with generative music — I've listened to a lot of it, and I love plenty of ambient work that's very nice, but we agreed quickly that we didn't want to make an ambient piece. That would have been interesting too, but we wanted the music to carry forward the same narrative we were telling visually — a real foundation, not just texture.

We talked about The Disintegration Loops by William Basinski, which you mentioned on the show before — it's about the exact same topic, the physical decay of a recording tape wearing out over time, with a short phrase playing over and over, getting more distorted each time. That's where we started: taking snippets from Toccata in D minor and transforming and distorting them over time to tell that story of decay. Then we thought, what if we added some notes here and there — fills — to make it more interesting, to tell more of a story rather than just replicating The Disintegration Loops. That's how we ended up building this whole generative music system.

It's built very much around the idea of jazz. In jazz you have a set structure — part A, part B, defined chord progressions, defined scales — and that's what Toccata builds on too: different parts, different scales. What I found really interesting was playing with the scale between composed and generative. Some of the musical variations in Toccata are much more composed, where we defined almost every note, with some parts filled in randomly and layered on top, producing real complexity. Other variations are completely generated.

Early on, we gave each variation an arbitrary name just to identify it. I remember the moment I was typing the name for the first fully generated one — that was exciting, because I'd tried writing generative music systems for years and they always sucked, and I never put one out into the world.

Entretiempos — Marcelo Soria-Rodríguez

Marcelo Soria-Rodriguez: Yeah.

Andreas Rau: This time was different because we had a clear foundation: composed parts that we could enrich with generative elements and vary over time. Coming back to jazz — you play through the theme once or twice, then improvise. That's basically what Toccata does: it improvises on top of a given scheme, given chords or chord progressions. And I think it works.

Marcelo Soria-Rodriguez: It does work.

Will: What are your favorite variations? I'd love to know.

Andreas Rau: That's really hard to answer. I've listened to all of them over and over. A couple of weeks before release I had a breakdown where I thought, I hate all of them, I never want to hear them again — we kept tweaking them, playing with the effects, and so on. Things played out well in the end, but I honestly can't say I have a favorite.

Marcelo Soria-Rodriguez: I agree completely. I had the same moment of "I can't listen to this anymore," from debugging — reload, reload, reload, hearing the same music again and again. Visuals don't wear on you the same way; you don't get fed up looking at something quickly, but audio is different. It made me think about how the pieces always start from the same position, and most people don't stare at a piece for one or two hours, so they never discover the variations that happen later on.

Entretiempos — Marcelo Soria-Rodríguez

That was a conversation we had late in development, not far from release: until then, the pieces played out their pre-composed sections before moving into improvisation. But after hitting reload too many times, we realized it's much better to let them roam freely in the musical landscape and see where they take you.

I don't have a favorite either — it depends on the moment, and some variations pair better with certain visuals than others, so it's really about the combination. What's most interesting is that even if I have a favorite at a given moment, listening to the others will always surprise me eventually. That's the beauty of generative art — and of hearing it happen in generative, or generative-ish, pre-composed music. I don't know quite what to call it, but I remember the first time Andreas upgraded the sound system and said, "I did this and that, now we have these new possibilities" — I heard the first result and told him: this is the first time I've heard generative music I'd actually choose to listen to. It has musical meaning; I can attach a feeling to it. Right now you can build beautiful A.I. models that mimic Bach or Beethoven convincingly, but they're completely lacking in soul. I found soul in the music system we built for Toccata. There are moments where it just breaks your expectations, and that's what I love discovering — not just "I like this theme," but the whole thing evolving, which is what makes me sit down and really listen.

Will: I almost don't want to share our favorites after those answers, but in preparing for this conversation, I came to really appreciate the minimalism of Andante con Moto — how sparse it is relative to the others. Every time I'd load one up and let it run for a while, other elements would gradually come in, and I loved that.

Trinity: My favorite is Vivace con Grazia, with that deep bass note keeping you steady throughout — I could listen to it forever. It's maybe slightly more ambient than the others, and it just sits in my soul in a strange way. All the other pieces are great, but that one hits me hardest, in the best ways.

Andreas Rau: That's really touching to hear. Thanks for sharing that.

Marcelo Soria-Rodriguez: Thank you.

Entretiempos — Marcelo Soria-Rodríguez

Trinity: Marcelo, you mentioned the time element earlier — it sounds like you introduced it because you didn't want people always hearing the pieces from the same starting point. How did you arrive at the practice of implementing a timestamp, so the piece always exists in time rather than always starting from the same spot — like you're just poking your head into the door of an amazing concert already in progress?

Marcelo Soria-Rodriguez: Ever since we thought that it would be a piece with cycles of degradation and blooming—getting old and getting young again, let's say—the truth is there's no other way to do the piece than by having it live an eternal life with cycles, and you just happen to be there in a moment of that cycle. If you always start from the very beginning of the piece, it's very hard to experience the decay we were thinking about. As we said earlier, this was a topic that already interested us, so the idea clung on to the project very strongly.

Finding the technical way to do it was just a matter of doing it. Once you know the concept you want, there are technical aspects to work through, because the visuals and the music have slightly different ways of timing themselves, and we tried to make them work together as much as possible. At some point we decided the piece would have a birth date, and that would set everything—the reference point. Because if you open the piece today, what does "today" even mean? Today means we look at a calendar and we know what today is, but the calendar itself is the reference. We needed a reference, and that birth date was the important thing. From there, you just count the time elapsed and let it affect all the control signals of the piece. The concept, in my opinion, is very natural—if you're thinking about cycles of decay and degradation, the piece should actually work like that.

Andreas Rau: What I find really beautiful about this way of engaging with a piece is that you always have a window into something. Like you were saying, it's like peeking into a concert hall and just listening to a little part of the performance. I really like to think of Toccata as a performance, actually—not a static piece, not a fixed piece by any means. It's living. It's going to be different each time you watch it, even though there are similarities, obviously. When you talk to a music performer, of course performances are going to be different every time—affected by mood, by the audience, by the venue, and so on. Having this in a generative piece, this window into our computers, I find that really beautiful.

Marcelo Soria-Rodriguez: We talked a lot about creating a piece that would foster spending time with it, which isn't so common. That also makes the piece harder to experience, because it demands time. A static image is instant—of course you need some time to look at the details, but your vision captures the whole piece at once. It's immediately there. But with something that happens in time, you need to spend time to fully experience it. And if you go back and experience the same thing again, it might lose some of its interest.

There are wonderful videos you just want to watch again and again. But we thought the experience could be very different if you go and see the same thing, but different—like Andreas said, a musical performance. I can watch the same concert by the same composer five times because I love it, and every time I'll find new nuances. Here, the differences are even bigger. It was interesting to let the piece be different at different moments in time and let it evolve—it also gives you room for different reactions to it.

Entretiempos — Marcelo Soria-Rodríguez

I don't know how to properly explain this, but your emotions take place in time. Your cognition takes place in time. If you only take a single fraction of time, there is no emotion, because emotion is an evolving thing—the biochemistry of emotion happens over time. There's no such thing as a photograph of your emotion; emotion cannot be frozen. The piece plays into that. It evolves because everything has to progress—because the notion of stillness, the notion of permanence, is false in nature and in reality. And so the piece also has to move forward with time.

Will: That makes this next question feel really appropriate. Considering the piece is so dynamic—however you're feeling, wherever it is relative to its birth date—did you ever imagine how it might be displayed? Did you picture it in a museum, on a projector, multiple screens side by side? Are they meant to be contrasted, or are they meant to be individual, solo experiences—where having multiple is great, but each should be evaluated on its own? We talked with a collector recently, LeMonde2D, about exactly this—how much thought he puts into displaying work digitally versus physically, through printouts or, in a case like Toccata, through screens. So what's your vision for how people should view it?

Andreas Rau: We haven't actually talked about this—this is going to be interesting. Each iteration of Toccata is so strong on its own that I personally would prefer it displayed one at a time. One screen. Especially because the music is such a vital part of the piece, you can't have multiple pieces of music overlapping in a room—it would be total chaos. I'd imagine one room, one screen or a projection, and decent speakers. That's how I'd like to experience Toccata personally. I haven't set up that space yet, but I really should. That'd be nice.

Marcelo Soria-Rodriguez: I fully agree there's no way to display multiple Toccatas publicly next to each other, because of the music. This was a recurring theme throughout development—when we were devising the ability to save an image to your hard drive, it felt very incomplete. We left that option in because it's almost a default expectation nowadays, but we put much more effort into letting you extract a full piece of the work—visuals in motion with music. If that hadn't been possible, we probably would have removed the image-saving option entirely. Saving just a video without the music would have been unthinkable, because the music is the piece—it's not an extra, it's the whole thing combined.

So to me, it's not possible to experience the piece only visually. If you had multiple screens, you'd need multiple sets of headphones so people could connect individually, if you wanted a shared experience across several screens. But to me it's a personal thing. I love enjoying it on my laptop with headphones, or with loudspeakers—that's very nice. But a proper setup with a decent screen and decent loudspeakers, that's something else entirely, and it's something I still haven't done myself. I've only projected it once, on a wall, with my laptop speakers—not the best setup.

The experience is very personal. Even at a concert with a thousand people all listening to the same music, everyone processes it differently. With visuals and music together, having many playing at once would be like listening to two songs simultaneously—you can't do that. Because of the time aspect, if you're going to experience it, you experience one. You can shift to another, or go to the next room. I doubt anyone will devote many rooms to Toccata, but who knows—if anyone does, please send pictures. Videos, even.

Entretiempos — Marcelo Soria-Rodríguez

Trinity: I'm just imagining a dinner party where you go through a bunch of different variations—let each sit for thirty minutes, then move on. Dinner and a show.

Andreas Rau: It's also really nice to just play Toccata from your phone—I've been doing this a lot lately. I was at the hospital with a newborn, and I played Toccata a few times because she actually recognized the music and reacted to it from pregnancy. It was obviously the music she'd listened to the most, by far.

Will: That's super cool. It was such an amazing innovation to include the ability to record from the piece—so simple, just pressing R, and pressing it again gives you a full clip, downloaded. It was seamless, and it made it easy to start sharing clips early on, especially while the project was queued before the auction started. People were flipping through variations, recording, and sharing them in Discord. I know there's a next step coming too—the ability for people to mint those clips into their own pieces. Can you tell us where Toccata is going from here?

Andreas Rau: As you said, we're planning to set up a system where collectors can extract a slice of time from Toccata—a window into the piece they collected—and Marcelo and I will mint it. It's still in progress; we haven't finalized it yet, but hopefully it won't be too long. Give us a couple weeks—things need to ripen, as we said, take a bit of time, and it'll be good in the end.

What we think is really nice about this recording system isn't just the shareability, though that's wonderful too—it's that you can relate to one moment more than others in Toccata, which is totally fine. It's evolving, it's changing. Life isn't beautiful every day—some days you're tired, some days you're pissed off, some days you're really happy, and some days you want to play something over and over again. The idea of having these slices of Toccata minted, so you can showcase the moments you really like and appreciate, was important to us. That's why we decided to build in this possibility.

Marcelo Soria-Rodriguez: I want to stress one more point: the ability for a collector to select their moment in the piece probably changes how they experience it. It's no longer just a spectator's point of view — it becomes yours. Like Andreas says, this clip is my happy part of the day. The day has a lot going on, but this is the part I choose, the part I get to select and hold in my gallery, my wallet, whatever. That creates a new relationship to the piece and gives you room to experience it further.

To me, one of the nice things about making art is helping people be in touch with themselves. That's always my reaction when I experience a piece of art I really like — any art form, but maybe especially music. Certain pieces move me so deeply, and when I spend more time with them, that feeling only grows stronger. So giving collectors this option might trigger some extra interest, some extra time spent with the piece, and that exploration might be good for them. I'm not saying it's some grand statement — but I do find it interesting that letting someone explore a piece in different ways can deepen the experience.

Trinity: When Toccata first came out, people were obviously exploring the music, but I think the number one thing we saw was people creating a deeper connection by choosing a date. "This is what it'll be on New Year's." "This is my birthday." "This is what Toccata looks like when I'm 100 years old, or 500 years old." It gives you a window into a time when you may no longer be here, or a moment of real significance in your own life.

The music part is obviously important — finding what resonates with you — but it's also about how people relate to a particular window of time. No matter what that moment sounds like, we can't go back and change our past. That was what was happening on a particular day, at a particular time, for better or worse — it was our lived experience. People have really responded to that.

Will: Collectors won't be able to mint as many clips as they want. By restricting them to only a handful, you put us in a position of sitting with the piece and curating out the two or three that really speak to us as viewers. That restriction is actually really wise — it forces you to be more thoughtful than if you could just mint unlimited clips. I really appreciate that.

I'm wondering if you'd both indulge a couple more random questions about the project before we wrap up — if that's okay, and Andreas, if you don't need to go take a nap.

Andreas Rau: I'm fine.

Will: One thing that's a little more nuts and bolts: obviously there's the visual element and the music element, and fx(hash) limits you on file size. Was there anything you originally intended for the project that had to get scaled back to fit fx(hash)'s constraints, or was that never really an issue?

Andreas Rau: I actually found it a very fruitful constraint. Since we were working with samples, the sound files take up space, obviously, and at one point we started adding different instruments — different layers on top of the music. We probably could have gotten away with it within fx(hash)'s restrictions. But then the question became: should we? Should we really not just stick to the basics — the piano, this very restricted aesthetic? That's what we decided to do: not add more, but keep removing and removing until we had the bare minimum — the piano, some effects, a few small additions here and there.

You've probably read about it on the project page — it's a special piano, the one I learned to play on as a kid. I sampled it this summer, and that was one of the very organic moments in creating this piece. I was spending a few days at my parents' place, not intending to do any work, when it just occurred to me: I need to record this piano, right here, right now, and it needs to be in Toccata. I got really excited and told Marcelo, and he said, "Oh yes, we need to have this." The sound quality probably isn't the best in the world, but to me, Toccata was never about sound quality — it's about that connection to the soul Marcelo's been talking about. We managed to create something that at least talks to my soul.

So, coming back to your question: it was really healthy to have that restriction in place, to not be able to dream too wild and say, "Let's have a full orchestra, let's sample violins and everything." Instead: let's reduce it to the very minimum that speaks to our souls.

Marcelo Soria-Rodriguez: I concur.

Will: Trinity, anything else you want to add?

Entretiempos — Marcelo Soria-Rodríguez

Trinity: This conversation has been so wonderful and enlightening. You had such an excellent write-up on the piece too, which Will was very happy you released—

Will: Before the drop.

Trinity: Before the drop. It goes into so much depth and detail, but hearing it from you two live, having this conversation, takes it to a whole other level for me, because you're sharing so much. That feels very in line with the piece itself. I think it's fitting that this is the first piece we've done a deep dive on like this — when we've talked to artists before, it's been about their work in general.

Will: Right.

Trinity: This time it's appropriate that our first deep dive is for Toccata specifically.

Will: It's really awesome this worked out — thank you both for coming together so quickly and finding the time to do this. I think this is a good place to wrap up. Is there anything we didn't ask that we should have?

Entretiempos — Marcelo Soria-Rodríguez

Andreas Rau: There's one thing we touched on but didn't really get into — the write-up, the little article we posted before releasing the piece. We're actually working right now on a more in-depth version of that article. It was written pre-release, so there was a lot else to take care of at the time. But there will be an extended version coming out sometime soon. When, who knows — but it'll be there, and we'll let you know.

Marcelo Soria-Rodriguez: Nothing more to add on my side, except to say it's an honor that you'd be interested in doing a full show about one piece. Thank you for that.

Andreas Rau: Really, thank you so much.

Trinity: One last question: if you had to collaborate again in the future, would you work together again? Was it a good experience?

Andreas Rau: I can wholeheartedly say yes. I'd love to create the fugue after the toccata. Who knows?

Marcelo Soria-Rodriguez: Yes, I would too.

Entretiempos — Marcelo Soria-Rodríguez

Will: Thank you both, Andreas and Marcelo. It's such a pleasure to have you — I think you've inspired us to do more shows like this, where we deep dive on a single project. This was really fruitful, and I think everyone's going to enjoy hearing directly from you about the piece. It's a special one to both of us — we were so excited to collect it and to talk about it on the show. And of course, we'd love to have both of you individually for a regular artist interview sometime too — no pressure, we'll work that out another time.

So that's Toccata. That's Andreas and Marcelo. Thank you both again. We hope everyone enjoyed listening. Later.
