'Le Ballet mechanique'

In 1924, American composer George Antheil wrote an elaborate score for the dada film "Le Ballet mechanique," involving 16 synchronized player pianos, three airplane propellors and a siren, along with other instruments. Antheil could not perform the piece as he envisioned it in his day, but thanks to the work of MIDI scholar Paul D. Lehrman and the musical robotics collective LEMUR, the first all-mechanical performance of this piece is showing daily in the National Gallery of Art's East Building until March 29.
