OK – Mozart obviously didn’t write any theremin concertos – but Peter Pringle’s rendition of main theme from the Andante movement of Mozart’s Piano Concerto #21 in C Major fixes that.

This is a theremin transcription of the theme played on the Moog Ethervox theremin. The theme was used in the soundtrack of the 1967 Swedish film, Elvira Madigan, and since then it has been called The Elvira Madigan Concerto.
