I think that this performance with the Thingamajigs is going to be an exploration of the acoustic space and particularly the vertical space, which we don't think about so much.

I had invented my own system, my own way of making electronic music at the San Francisco Tape Music Centre, and I was using what is now referred to as a classical electronic music studio, consisting of tube oscillators and patch bays. There were no mixers or synthesizers. So I managed to figure out how to make the oscillators sing. I used a tape delay system using two tape recorders and stringing the tape between the two tape machines and being able to configure the tracks coming back in different ways.

People's experiences are all different, and you don't know what the person experienced. They know, but you don't, so I think it's important to listen carefully to what a person has to say. And not to force them into any direction at all but simply to model what you've experienced, model it and also be what I call a Listening Presence. If you're really listening, then some of the barriers can dissolve or change.

Listen to everything all the time and remind yourself when you are not listening.

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.

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.

The sound that I play is delayed, it's modified, and it's modulated. It's an intelligent system; it's happening now.
