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."

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 think I sent one [book] to Brian Eno. I don't know how I got to know his address, but I sent one to him. He called me up and he said, "I really like the book, and I'm starting a new label, would you liked to do something?" It was a tricky situation for me, because I've always had this thing in my life of a tension between collaboration, which was extremely important to me, and then being alone. Make of that what you will!

One of the things about grief - I wouldn't generalise, because everybody responds to tragedies in different ways - but I had a huge amount of energy.

I do still have dips of confidence or [can think] everything I do is rubbish.

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

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
