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.

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.

The mission [of institution] won't change. It will continue to be what it is: to spread the practice of deep listening and introduce it to people, to do workshops and retreats and certification programs and so on.

I didn't have any sophisticated equipment at all. The equipment we had in the studio at the time was not intended to make music; it was for testing purposes. So we had to repurpose all the equipment to make music. That made me try a lot of different things.

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 to cope with attitudes that were not supportive all along. I mean, you still have that.

Maybe I'll start from the initial idea, what motivated me to do that. In 1953, I had access to a tape recorder. Tape recorders were not widely available. There was no cassette tape back then. It was a Sears Roebuck tape machine. I put a microphone in the window and recorded the ambience.
