One interesting thing - I play bass and guitar and stuff like that. I know those instruments really well. But I don't know how to play clarinet or trombone or any of these other instruments. I don't actually know how to play ukulele even though I've played it a lot in the past. Because of the weird tuning it's not exactly like a guitar. That's one of the reasons I like that instrument - it makes for surprises. It's not so predictable as the bass or the guitar is for me.

Writing for chamber ensemble is the thing that excites me the most. So when I went down into the cistern, I didn't know that I was going to make a record based on that time and those improvisations. But as soon as I started playing music down there, I realised that it was going to be something significant for me.

It's kind of like being a writer in the sense that you always hear other writers say, 'Well, the best way to start writing is to just start writing.' The same goes for improvisation. You want to start improvising, just start playing notes. And the more you do that, the more comfortable - or not comfortable - but I guess how you're able to adapt to situations. You become more familiar with your instrument. As soon as you have a musical thought, you can go ahead and add to that musical thought and know your way around.

I can start playing ukulele and then I'll go to a note that I think will be there, but because of the tuning, it's a completely different note. That excites me. That's why I had the ukulele around in the first place, years ago. It was to just break out of habits.

I did one year of school and I was doing correspondence school, which was actually another happy accident. Correspondence school is basically home school, but you teach yourself instead of your parents teaching you. I found that to be one of the most important things in my life is that I learned how to teach myself things. I feel like that's something that schools should actually teach.

People always say that music is a universal language. It was very, very true. We could show up anywhere with any people speaking different languages and we could just be like, "You want to play that song? Yeah, okay." We would usually want to play Latin American songs, and they would usually want to play Santana or Jimi Hendrix and stuff like that. So we would trade off. So yeah, we were able to make a lot of friends that way and meet a lot of local musicians. It was a great experience.

Usually when you're playing with other people in not such a reverberant room, you have to be quick on your feet and think about stuff really quickly. But inside the cistern, it was almost like I was at home on my computer arranging and taking time thinking about the next step, the next note. Instead, the room was my collaborator. I could hear the note and sit there and think. I could be arranging as I was going in real time, which was fascinating.
