Something that I did, and I developed out of that sonic meditations, which were pieces that I composed in the '70s that now are very well-known and used in many classrooms all over the world, but at the time were outrageous.

Before that, an 8-bit recording was pixelated; it was really bad. It didn't serve what I was doing, which was recording live sound and delaying it and feeding it back. This is essentially what the EIS system is: a bunch of delays.

I am also interested in music expanding consciousness. By expanding consciousness, I mean that old patterns can be replaced with new ones.

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.

In the beginning we were making tape music, meaning, we were making music on tape.

It takes time because the habitual response to that is very deep. It goes back to our earliest responses as babies. You have to feel safe, and if a sound is threatening, you're going to be upset. There are those early responses, depending on how and what kind of experiences you had.

[Students] they did the sonic meditations, I would observe them in their ensembles, and the ensembles improved incredibly. So I knew I had something to do and something to say.
