Quite often, and in fact more often, I would say, I'm struggling all the way through to think, "What is it I like about this? What is the personality of this thing I'm hearing that I like so much?" And it's nearly always a sort of mixed emotion, which is why I like it. It's something that I have mixed feelings about in the sense that it's both, say, placid and dangerous, or bitter and sweet, or dark and bright.

You know that in order to copyright material somebody has to write it down for you. Any piece of recorded material has to be scored in order for it to be copyrighted. I've seen the scores of my things and they don't resemble the music in any way. If you give them to somebody who has never heard the music and say, "What does this sound like to you?" they'll play you something that has no relationship with the music it derives from. Notation simply isn't adequate.

What happens with notation is that it reduces things to a language which isn't necessarily appropriate to them. In the same way that words do, you get a much cruder version of what was actually intended.

Of all the things you can now do, which do you choose to do?

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.

John Cage made you realise that there wasn't a thing called noise, it was just music you hadn't appreciated.
