My relationship with the journalists who covered the campaign was complicated. I often hid from the critical eye of their cameras and their omnipresent digital recorders wary of the critique implicit in every captured moment. But I also grew to respect and understand their passion for their work their love for the journey we were sharing.

I got interested in the idea of music that could make itself in a sense in the mid 1960s really when I first heard composers like Terry Riley and when I first started playing with tape recorders.

Computers have virtually replaced tape recorders.
