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.

Paul [ Burwell] and I had also got interested in making books. We'd been working with Bob Cobbing, the sound poet, since the beginning of the 70s, and Bob had this press called Writers Forum.

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".

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!

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.
