I don't mean I give the same intensity to everything I do - if I did that, I'd be dead, but I'm very conscious, I make notes, and I have a fairly good idea of what's happening in my life.

We drank quite a lot and Tony Harrington said, "We're thinking of starting a record label at The Wire; how about you do a solo record?" I said, "Well, how am I going to do that?" I thought about it, and I'd been working on a lot of music in the years before, and I was working as a journalist, full time, really, up until that point; in whatever little spare time I had, I was working on music. So I said yes.

I had the idea to do an anthology about instrument-making.

At that time, 73 and 74, I became aware that there were a number of us making instruments. Max Eastley was a good friend and he was making instruments, Paul Burwell and I were making instruments, Evan Parker was making instruments, and we knew Hugh Davies, who was a real pioneer of these amplified instruments.

I was associated with the Artist Placement Group in the early 1970s and David Hall, the video artist, was an Artist Placement Group artist. I was completely broke at that time, and he said to me, "Come and do some teaching" - he was head of department at Maidstone College of Art. And I went and did a couple of teaching days and practically the only person who showed up was David Cunningham [Flying Lizard's main man], with all of this finished work

I had ideas about music and sound and listening and time and so on that I wanted to pursue as an individual, and by doing that book, Brian [Eno] opened the door, and he decided to do a record based loosely on the book.

One of the nicest things is that I still get, very ambiguously, people saying to me, "Oh, I'm just reading your book." And I say, "Which one, for God's sake, I've done six now!" "Oceans of Sound".
