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.

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.

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.

Arranging is sort of the most exciting part of making music right now for me. I really enjoy the process of arranging because you're given all the time that you need to decide on every single note.

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.

Being raised on a boat felt like it was totally normal to me. I was just another kid hanging out, doing this and that. My girlfriend and I had a funny period of time where I was always wanting to hug her all the time. I looked at my brother and he's the same way. It wasn't that our family was necessarily more affectionate than others. It was that we were basically sitting on top of each other, or side by side squished in together all the time. Because the boat was that small. It became part of our nature to be close to people.
