Query: Theremin-An Electronic Odyssey

This was an impulse buy, and I am not sure what I was expecting. This is a documentary about the early years of electronic music and the invention and developoment of the theremin. We meet Leon Theremin and his protege Clara Rockford and witness there re-unification after Theremin was allowed to leave the Soviet Union. It was interesting to watch them perform on the Theremin, but the latter half of the movie is disappointing as Leon & Clara are both so old that I am wondering what I am watching. Leon falls asleep in a taxi on camera at one point. I recommend this to anyone who is interested in the history of electronic music.
