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.

One night, I pissed into an empty wine bottle so I could continue watching Monty Python, and suddenly thought 'I've never tasted my own piss,' so I drank a little. It looked just like Orvieto Classico and tasted of nearly nothing

Sometimes you recognize that there is a category of human experience that has not been identified but everyone knows about it. That is when I find a term to describe it.

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.

You just make different music on a computer. And you can make wonderful music on a computer, but don't pretend that the machinery is transparent. It makes as much difference to what you're doing as it does if you play an acoustic guitar as opposed to a kettledrum. You're not going to make the same music.

If something is good, you must torture it mercilessly until it is either dead or great.

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.
