One day I decided I would like to put a record into my system. So I picked up a record that was lying on the table, and put it on. I didn't bother to look at what it was because I didn't care, and it turned out to be Madame Butterfly. So I processed the aria from Madame Butterfly in my system and I played with it.

I try to schedule the Intensives wherever I go.

Now, I have about twenty per hand and can change the number of delays, change different parameters, the delays to the modulations and so forth. I developed the EIS over the time period that I was just talking about [1991].

I have a commission to do a piece in a place in California, Oliver Ranch, which has an eight-storey structure called The Tower designed by the visual artist Ann Hamilton.

I can't really deal with buttons. And that's what I keep saying, "Okay, I can't push buttons, because that means I have to take my hands off the keyboard or the buttons or whatever. Don't you understand!" .

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.

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