Deep Listening is listening in every possible way to everything possible to hear no matter what you are doing. Such intense listening includes the sounds of daily life, of nature, or one's own thoughts as well as musical sounds. Deep Listening represents a heightened state of awareness and connects to all that there is. As a composer I make my music through Deep Listening

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.

Listening is not the same as hearing and hearing is not the same as listening

There are these sounds that come from outside that work really well if you're listening. If you're not listening, if you're blocking them out, then you don't get it. You don't get the merger of what the players are doing with everything, listening to everything.

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.

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.

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.
