Switched-On Bach is a musical album by Wendy Carlos (then Walter Carlos) and Benjamin Folkman, produced by Carlos andRachel Elkind and released in 1968 by CBS Records. It played a key role in popularising classical music performed on electronic synthesizers, which had theretofore been relegated to experimental and "pop" music. This fostered a significant increase in interest in electronically-rendered music in general, and the Moog synthesizer in particular.
Switched-On Bach was one of the first classical albums to sell 500,000 copies, and go platinum (Van Cliburn's recording of Tchaikovsky's Piano Concerto No. 1 went triple-platinum in 1958). Entering Billboard's pop Top 40 charts on March 1, 1969, it climbed quickly to the Top 10; it stayed in the Top 40 for 17 weeks , and in the Top 200 for more than a year. In the 1970Grammy awards, the album took three prizes: Best Classical Album, Best Classical Music Performance, Instrumental Soloist(s) (With or Without Orchestra) and Best Engineered Classical Recording.
