 Although the term "flexatone" is used, the second movement, "Andante con anima", is one of the few classical pieces to make use of a musical saw, although this instrument is often omitted in performances and recordings of the concerto.The third movement, "Allegro brillante", caps the piece in an exciting manner.The concerto was first recorded in 1945, by Moura Lympany with the London Symphony Orchestra under Anatole Fistoulari, and again the following year by William Kapell with the Boston Symphony Orchestra under Serge Koussevitzky.
