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!

If I'd thought, "I can't really play this instrument," I wouldn't have done it! But I didn't care, you know. I didn't care!

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
