It wasn’t documented! :/ one of the things I learned only after my prolific college years is that despite what Cage says, if you don’t document, it didn’t happen.

If it’s at all interesting I’d add that the instrument was multichannel and I performed from a seat in the theater audience, with the outputs of the system variously directed to the quad-channel PA and to the battery-powered car stereo I had sewn into a nylon vest / jacket on my person.
