Being completely free to choose what to do is actually quite difficult

The seven white notes on the piano - each section of the piece (there are 12 sections) is five of those seven white notes. If you calculate it, there are 21 groups of five notes in any group of seven notes. And although there are 12 sections, this piece actually uses nine of those groups because some of the sections repeat earlier ones. So that's the formula. It's very simple as a way of generating something. It's my inner minimalist.

When you sing with a group of people, you learn how to subsume yourself into a group consciousness because a capella singing is all about the immersion of the self into the community. That's one of the great feelings - to stop being me for a little while and to become us. That way lies empathy, the great social virtue.

Rationality is what we do to organize the world, to make it possible to predict. Art is the rehearsal for the inapplicability and failure of that process.

I've always thought that art is a lie, an interesting lie. And I'll sort of listen to the "lie" and try to imagine the world which makes that lie true...what that world must be like, and what would have to happen for us to get from this world to that one.

I'm bloody awful at multi-tasking.

You feel as if you're not living a full life. Which, of course, is why - it's my theory about why so many people who are heavily into computers are also into extreme sports and S&M. It's because their bodies are crying out for some kind of action.
