When you build a building, you finish a building. You don't finish a garden; you start it, and then it carries on with its life. So my analogy was really to say that we composers or some of us should think of ourselves as people who start processes rather than finish them. And there might be surprises.

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 often say to people that producing is the best paid form of cowardice. When you produce things you almost always get credit, if it's a good record, but you hardly ever get the blame if it's not! You don't really take responsibility for your work.

I've discovered this new electronic technique that creates new speech out of stuff that's already there.

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

We are increasingly likely to find ourselves in places with background music. No composers have thought to write for these modern spaces, which represent 30% of our musical experience.

I got an amazing 10-CD set, it's the music that Alan Lomax recorded in Haiti in 1936. And what's incredible is how fantastic the drummers are and how off-the-grid they are. The liveliness is astonishing; they're just totally alive, these recordings. It's very interesting, to me, to be reminded of that, that there was a time when things were not that tight.
