You run into stereotypes so that the stereotype filters who you are and what you do, and having to deal with that was the most frustrating thing for me.

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.

My first tape piece was made with that Sears Roebuck recorder. I modified sound using cardboard tubes with a microphone in the end to filter the sound. I had a wooden apple box with a Piezo [contact] mic and little objects that I could amplify on the box. I used the bathtub for reverberation.

Deep Listening is listening to everything all the time, and reminding yourself when you're not. But going below the surface too, it's an active process. It's not passive. I mean hearing is passive in that soundwaves hinge upon the eardrum. You can do both. You can focus and be receptive to your surroundings. If you're tuned out, then you're not in contact with your surroundings. You have to process what you hear. Hearing and listening are not the same thing.

I noticed you could monitor the recording that you're making, but you could also monitor the playback head. There's a little distance between them and so you get an echo, right? If you change the amplitude of, say, the playback and play with that, you get different qualities and different sounds. So I was very interested in that phenomenon.

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 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.
