Clara Rockmore: The Greatest Theremin Virtuosa (1998)

Quite simply the finest theremin player who has ever lived, Clara Rockmore began her performing life as a violin prodigy at the age of 5 years old, still the youngest person ever admitted to the prestigious Imperial Conservatory of Saint Petersburg where she studied under the great Leopold Auer. Due to childhood malnutrition causing bone problems in her teen years, she was forced to give up the violin and moved to New York City in the mid 1920's where she met and became involved with Russian electronics genius Leon Theremin and helped him to refine and perfect his new instrument, giving advice from the standpoint of a musical performer to make the theremin more playable and developing her own hand techniques and exercises for playing the instrument.
