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

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

I became interested in the delay, having sounds recorded and played back and then come back. I did many different configurations of sending signals from one track back to another track, or to the same track, or crisscrossing them and so forth. I worked on masking the delays so when I played into the machine, I would make long tones and collect sounds in such a way that you didn't hear the delay, although sometimes you did.

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 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.

I'm very interested in vertical space.I want the players to listen to their sound in such a way that they hear the complete sound they make before they make another one. So that means that they hear the tail of the sound. Because of the reverberation, there's always more to the sound than just the sound.

After a long section of the glass playing, you'll hear an instrumental sound emerge from some undisclosed location. There'll be a lot of mystery about the sound, I think.
