Electronic music pioneer Robert Moog, inventor of the Moog Synthesizer, died Sunday at 71. We all owe Moog a debt for revolutionizing popular music, starting with Wendy Carlos' "Switched on Bach" (1968) up through countless rockers in the 60s, 70s and 80s. Closer to Disney fans' ears, Wendy Carlos used a Modular Moog synthesizer to perform the score for TRON (1982). And the Moog put the "electric" in the "Main Street Electric Parade." Rest in peace, Bob; we'll keep dancing to your electronic beats.
