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

I'd entirely forgotten about Pass The Distance, and then I went to Japan in 2000, and was asked to do interviews with all these journalists, who were showing up with bootlegs of this record, asking me to talk about it. I was astonished. It kind of gained momentum.

Dub music is like a long echo delay, looping through time...turning the rational musical order into an ocean of sensation.

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 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 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!
