This is the same theremin style used by Lydia Kavina in the Big Briar video, Mastering the Theremin . Several people ran screaming looking for the nearest asprin vendor, but many stayed and fought back tears as they patiently waited their turn to wail. It was chaotic, but beautiful. Sadly, we did not record the event. It wouldn't be too hard to duplicate though - just set a bunch of theremins up in a pasture and stampede your herd of cattle through them.
Several pictures are available.
Now, all these disillusioned folks who now thought the theremin was only for creating obnoxious sound- effects were finally given the chance to witness the true magic of Clara Rockmore and Lev Sergeyvich Termen. In general, the reaction was quite good and several people stayed after the show to try a theremin again. It's not every day that one gets to meet and talk witht the person who probably most inspired them to become an engineer - but I was given that chance. Dr. Moog was incredibly kind and informative throughout the entire day, and I cannot thank him enough for making the long drive to come talk to us. It was surely a day I shall remember for all time.
