Yes, that is Frank Zappa in the Polaroid photo above (the guy hugging him is not Kurt). In November of 1966, Professor von Meier organized the opening of a Harold Paris sculpture exhibit. Unfortunately, the sculpture was not available, but Kurt nonetheless managed to turn the event into an "installation" rather than an "exhibition." There were bands, including Zappa's Mothers of Invention, plus Canned Heat and other rock and roll groups. And a light show. And films. And all at the same time. As the article below from the UCLA Daily Bruin notes, it all "had a strange influence on the people there." As Kurt might say, "Ah, well."
