Those people who don't have any voluntary control, or hands, can work with the physical movement that they can do - whatever voluntary movement they have, even the slightest .

I felt a challenge to compose music. That's where my challenge was, for the most part.

The San Francisco Tape Music Centre was a kind of collective non-profit that my friends and I got started so that we could pool our equipment and make tape music.

Listening is selecting and interpreting and acting and making decisions.

When we had the San Francisco Tape Music Center, we had a couple of Ampex tape machines there, and I could string tape from one machine, past the heads, and over to the next machine to the supply-reel amp, and have another delay there.

There is a book called San Francisco Tape Music Centre:1960s Counterculture and the Avant-Garde and this book describes everything that you want to know or don't want to know about it, with a lot of documentation.

I have a variety of ways that I make music, but I'm working with the Thingamajigs in a particular way, which is: They are bringing to me their performance skills and their unusual instruments, which I'm relishing. They're really beautiful. The other thing is improvisation - these players improvise and they do it very beautifully, as a matter of fact.
