My father was always playing the piano. He played all kinds of music - Gershwin, all kinds of stuff. He was really a hugely encouraging force to me when I was little.

I split it up into working on the two narrative pieces that can tell a story. The scariest thing was whether I'd be any good performing live again. It was such a long time since I'd done any live work. It's so different for me than recording. Every night my audiences were what I would dream of. You could just feel their support.

I'd become very involved in the production, so the albums were taking longer. So it was never a deliberate decision not to do live shows. A few times, I've thought about doing them again, but it's just kind of never happened. I've just sort of gone the path of becoming a recording artist I guess.

My desire was never to be famous. It was to try and create something interesting musically if I could.

There are a lot of very strong connections with music and mathematics. They both can work in patterns and sequences and repetitions.

If you believe in what you do and you really want to be in music, just stick at it. It's always a learning process. Enjoy it because I think making music is a privilege, really. In an ideal world, it should also always be fun. As much as possible, make it fun.

When I'm a man, I will be an astronaut, and find Peter Pan on the second star on the right.
