Repetition doesn't really exist

Another way of working is setting deliberate constraints that aren't musical ones - like saying, "Well, this piece is going to be three minutes and nineteen seconds long and it's going to have changes here, here and here, and there's going to be a convolution of events here, and there's going to be a very fast rhythm here with a very slow moving part over the top of it." Those are the sort of visual ideas that I can draw out on graph paper. I've done a lot of film music this way.

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.

I'm always interested in what you can do with technology that people haven't thought of doing yet.

A studio is an absolute labyrinth of possibilities - this is why records take so long to make because there are millions of permutations of things you can do. The most useful thing you can do is to get rid of some of those options before you start

Most big concerts sound disgusting and awful and insultingly bad. It's like going to the cinema and been shown a scratchy film which is upsidedown and the bulb had gone on the projector. The quality of large-scale live music is so shocking.

Once I started working with generative music in the 1970s, I was flirting with ideas of making a kind of endless music - not like a record that you'd put on, which would play for a while and finish.
