The Musicians Union declared you couldn't mime on Top Of The Pops, which is obviously impossible, if you've got a studio-based record that you'd worked on for a year or something. And there were a lot of terrible performances. Because on Top Of The Pops, you were just thrown onstage.

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

We [with David Cunningham] did do Top Of The Pops. It was an eye-opener. I mean, one of the things that was so interesting - I've talked about this a few times recently, and people can't believe it - they used to do this thing called tape switch with the Musicians Union.

I'd been listening to African-American music since the first record I ever bought, which was by Sam Cooke. And it sounds more like my private thoughts that I never thought I would be able to articulate - I never thought I would be able to express publicly.

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.

I remember I did quite a lot of interviews when the book and the CD came out, and I did a drivetime interview for Radio London or something. You wouldn't immediately associate the music on Ocean Of Sound with drivetime radio, but people found things that they liked, and the DJ was playing some records at 5 o'clock in the afternoon on a weekday.The man who was playing them said to me, "That Peter Brotzmann track, it's like having your head boiled in acid."

Sound: always in a state of emergence or decay
