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.

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

There's a sense of trajectories that are extraordinary about a life like this. You can reconnect with people and go back to playing with them after years and years of not even knowing if they're alive.

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 working in, being a single parent with a grieving child of five years old. It was horrendous. I couldn't go out much, because I had my daughter to look after. So people used to come round, and Tony Harrington from The Wire came round.

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".

Every time when it comes to writing a book, I think, "I'm the last person in the world that should be doing this, I don't know anything, I can't do this." And I went through years of that with Into The Maelstrom.
