The whole point of art, as far as I’m concerned, is that art doesn’t make any difference. And that’s why it’s important. Take film: you can have quite extreme emotional experiences watching a movie, but they stop as soon as you walk out of the cinema. You can see people being hurt, but even though you feel those things strongly, you know they’re not real.

I think audiences are quite comfortable watching something coming into being.

If I tried to make a commercial album, it would be a complete flop. I have no idea what the world at large likes.

The tools are evolving, and people's interests are evolving as well. So, suddenly people like to hear bands, people like Devendra Banhart or the xx, bands that make a kind of virtue of sloppiness. That isn't what they would describe what they're doing, but the fact is they make a virtue of the sort of hand-made nature of what they're doing.

All cultures have these feelings about non-functional areas of activity. And the more time people have on their hands, the more they commit it to those areas.

I think the other thing that's important is getting to a place, which very, very rarely happens with improvising groups, where somebody can decide not to play for a while. You watch any group of musicians improvising together and they nearly all play nearly all the time. In fact I often say that the biggest difference between classical music and everything else is that classical musicians sometimes shut up because they're told to, because the score tells them to. Whereas any music that's sort of based on folk or jazz, everybody plays all the time.

Composition is a way of living out your philosophy and calling it art.
