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 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!

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.

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.

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

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.
