Ambient Music must be able to accommodate many levels of listening attention without enforcing one in particular; it must be as ignorable as it is interesting.

If you watch any good player, they're using different parts of their body and working with instruments that respond to those movements. They're moving in many dimensions at once.

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.

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.

My interest in making music has been to create something that does not exist that I would like to listen to. I wanted to hear music that had not yet happened, by putting together things that suggested a new thing which did not yet exist.

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.

In terms of what has been happening recently, there have been, I think, some really interesting new instruments that have come out that sort of show me the direction of the future. Korg has introduced the - they've had a whole series now of these things called Kaoss Pads. They're wonderful because they do get your muscles working again. And what DJs do, of course, with their DJ turntables now, the CD turntables, which have pitch change and speed change and everything else. They're doing something that I think is interestingly physical.
