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.

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.

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.

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.

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 remember being on Hawaii when I sailed to Hawaii. It felt unsettling to be walking around there because I was thinking, "This place could just sink at any second." In actuality, it totally can. But it really felt like, I am this teeny, tiny speck out in the middle of all that water, I feel so unprotected right now. It almost felt creepier than being on a boat, which is an even smaller speck out in the middle of nowhere. But I felt like I had some control over that situation.
