George Antheil (1900-1959), with his radical compositional style, created quite a stir in the '20s in Europe and the US. As the self-styled "bad boy of music," he dismayed his audiences by integrating the sounds of machines into his works. His famous "Ballet Mécanique" was written for eight pianos, four xylophones, two electric doorbells, two airplane propellers, four large drums, and sirens. At the time he met Hedy Lamarr, Antheil was working in Hollywood as a composer of film music.
