Doctor Phibes Clockwork Wizards - Art Garfunkel Eats Babies
Doctor Anton Phibes was a well respected, influential organist in the 1920s and 30s until the untimely death of his beloved Victoria threw him into a suicidal depression. After barely surviving a particularly gruesome attempt at his own life, the doctor vowed vengeance on the society that let his wife die.
Unfortunately for society, the doctor decided the necessary means of doing so was building a bunch of robot musicians who would live in his basement and play synthesized music really loud at all hours of the night. There goes the neighborhood.
