I’ve been reacquainting myself with the music of George Antheil. He had some success with his Ballet Mecanique, which was written as a score for an 16 minute art film in 1925. Interestingly, Antheil’s finished score was twice as long as the film it was written for and went on to have a life of its own as a concert piece. It called for 16 synchronized player pianos, which was not technically possible at the time, so he rewrote it for multiple pianists playing in sync as best they could. It also included airplane propellers, sirens and percussion. Here’s the 1925 film with Antheil’s music. Good luck!
