This is, in my opinion, THE theremin recording to have in your collection.  Ms. Rockmore's touch on the instrument is unbelievable.  Her command of dynamics and pitch on this notoriously difficult instrument is impeccable, all the more considering that this was recorded when she was 76 years old! We can only wonder what it was like to see and hear her in the 1930s and 1940s, when Ms. Rockmore played the Theremin as a soloist with symphony orchestras.
