This video, via Chris Stack (experimentalsynth), captures an overview and performance demo by Bob Moog of the theremin.

Here’s what Stack has to say about the video:

Many years before going to work for Moog Music as marketing manager I was a printed circuit board designer. I met Bob Moog in Asheville and wound up doing the PCB design work on his Multi-Touch Keyboard project. Around this time, Bob hosted a presentation called “New Vistas 91”, a look at some then current happenings in avant garde electronic music.

Bob was gracious enough to let me record the presentation on my then new Video 8 camera. The tape was lost for decades, but recently found and digitized. Unfortunately the audio and video quality is not great, but I feel this is very interesting from a historical perspective, and I offer it as such.
