In the '60s my friends were interested and we were hearing electronic music coming in on community radio from Europe, so that's where it started. And I had a tape recorder and started making things with it.

I used to go into the studio around midnight and stay all night.

All the way from the first thing that I can remember, like our Victrola - a wind-up record player - and my grandfather's crystal radio, and my father's shortwave radio.

I thought that it would be interesting to have a mirror and grab a light and shine it around in different ways. It's an analog to the acoustic reflections that we're going to be trying to activate as well.

I got very interested in attention and awareness and how to achieve certain states through understanding this.

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

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.
