|Wendy Carlos chronology|
Switched-On Bach is a musical album by Wendy Carlos (originally released under the name of Walter Carlos) and Benjamin Folkman, produced by Carlos and Rachel Elkind and released in March 1968 by Columbia Masterworks Records. It played a key role in popularizing classical music performed on electronic synthesizers, which had until then 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. 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 1969 Grammy Awards, the album took three prizes: Best Classical Album, Best Classical Performance – Instrumental Soloist or Soloists (with or without orchestra) and Best Engineered Classical Recording.
The album consists of pieces by Johann Sebastian Bach, performed on a Moog synthesizer, a modular synthesizer system, one of which can be seen at the back of the room on the album cover. "Switched-On Bach," or "S-OB" as Carlos referred to it, was recorded on a custom-built 8 track recorder (constructed by Carlos from superseded Ampex components), using numerous takes and overdubs. This was long before the days of MIDI sequencers or polyphonic keyboards. Recording the album was a tedious and time-consuming process—each of the pieces had to be assembled one part at a time, and Carlos, Elkind and Folkman devoted many hours to experimenting with suitable synthetic sounds for each voice and part.
Due to the monophonic nature of the Moog instrument, Carlos never had the option of recording multiple notes on the same track, and in the same take. The simplest chordal constructions required multi-tracking, synchronization, and perfect timing, adding greatly to the overall time consumed by the project.
Carlos—a highly proficient musician and studio engineer and a former student of Vladimir Ussachevsky -- worked closely with synthesizer designer Robert Moog throughout the recording process, testing his various components and suggesting many improvements. In 1968, not long before the album was released, Moog gave a paper at the annual Audio Engineering Society conference, where he played one of Carlos' completed recordings:
- "At the end of the talk I said to this fairly big audience, 'As an example of multi-track electronic music studio composition technique, I would like to play an excerpt of a record that's about to be released of some music by Bach.' It was the last movement of Walter's Brandenburg No. 3. I walked off the stage and went to the back of the auditorium while people were listening, and I could feel it in the air. They were jumping out of their skins. These technical people were involved in so much flim-flam, so much shoddy, opportunistic stuff, and here was something that was just impeccably done and had obvious musical content and was totally innovative. The tape got a standing ovation."
- "CBS had no idea what they had in Switched-On Bach. When it came out, they lumped it in at a studio press party for Terry Riley's In C and an abysmal record called Rock and Other Four Letter Words. Carlos was angered by this, so he refused to come. So CBS, frantic to have some representation, asked me to demonstrate the synthesizer. I remember there was a nice big bowl of joints on top of the mixing console, and Terry Riley was there in his white Jesus suit, up on a pedestal, playing live on a Farfisa electronic organ against a backup of tape delays. Rock and Other Four Letter Words went on to sell a few thousand records. In C sold a few tens of thousands. Switched-On Bach sold over a million, and just keeps going on and on."
Carlos followed the release of this album with a number of other classical Moog albums:
- The Well-Tempered Synthesizer (Columbia Records, 1969)
- Sonic Seasonings (Columbia Records, double disk album, 1972)
- A Clockwork Orange (Warner Bros. Records, movie soundtrack album, 1972)
- A Clockwork Orange (Columbia Records, extended synthesizer cuts from soundtrack album, 1972)
- Switched-On Bach II (Columbia Records, 1974)
- By Request (Columbia Records, 1975)
- Switched-On Brandenburgs Vol 1 & 2 (Columbia Records, 1979)
- Digital Moonscapes (Columbia Records, 1984)
- Beauty In The Beast (Audion Records, 1986)
- Secrets of Synthesis (CBS-FM Records, 1987)
- Peter and the Wolf - Carnival of the Animals with "Weird Al" Yankovic, (CBS-FM Records, 1988)
- Tales of Heaven and Hell (East Side Digital Records 1998)
- Rediscovering Lost Scores, Vols. 1 & 2 (East Side Digital records, 2005)
The album received a mixed reaction at the time of its release. Some critics reviled it for trivializing the work of one of the most revered classical composers of all time, but others were excited by the freshness of the sound and the virtuosity that went into its creation. Regardless of the negative reviews, the album caught the public attention and sold better than anyone had expected. Suddenly Moog's company found itself inundated with requests from record producers for Moog systems, and a rash of synthesizer albums were released to capitalise on the popularity of the new sound.
Some of these albums were similar to S-OB in being synthesized versions of classical pieces including:
- The Moog Strikes Bach by Hans Wurman (RCA Records 1969)
- Chopin À La Moog by Hans Wurman (RCA Records 1970)
- Switched on Gershwin by Gershon Kingsley & Leonid Hambro (Avco Records 1970)
- Everything You Always Wanted to Hear on the Moog* (*But were afraid to ask for) by Andrew Kazdin and Thomas Z. Shepard (CBS (Columbia Records) 1973)
- The Unusual Classical Synthesizer (ABC 1972) by Mike Hankinson—unusual in that it was performed on an EMS VCS3 synthesizer rather than the more typical Moog modular synth.
- Snowflakes Are Dancing (Clair De Lune) by Isao Tomita (RCA Red Seal Records 1974)
- Jon Santo Plays Bach (Synthesized Electrons) MCA Inc. 1976)
Others capitalised on the Moog craze by creating "Switched-On" versions of contemporary artists and other genres:
- Switched On Bacharach and More Switched On Bacharach by Christopher Scott. (Decca 1969)
- Switched-On Rock by The Moog Machine. (Columbia Records 1969)
- Music to Moog By by Gershon Kingsley (Audiofidelity 1969)
- Moog Plays The Beatles Marty Gold (Avco Records 1970)
- Switched on Country by Rick Powell (RCA Records 1970)
- Country Moog - Switched on Nashville by Gil Trythall (Athena 1970)
- Plugged-In Joplin by The Eden Electronic Ensemble (Pye 1975)
- The Age of Electronicus by Dick Hyman (Command Records 1969)
Columbia Records even entered the competition by releasing an all-orchestral album with the same playlist as S-OB, with humorous liner notes:
- Switched Off Bach by E. Power Biggs, Zoltán Rozsnyai, Pablo Casals & Glenn Gould (Columbia Records 1972)

- Note: the Adagio of Brandenburg Concerto No. 3 is a composition by Carlos and Folkman as an attempt to replicate Bach's most daring quasi-improvisatory style. J.S. Bach provided only a Phrygian cadence consisting of two chords (A minor and B) between the two movements in G major, and quite possibly intended this to be heard at the close of a keyboard improvisation.

The album has been released with two different covers. The most-common one shows a photograph of a man dressed as Johann Sebastian Bach standing in front of a Moog modular synthesizer. The very first pressing however showed Bach seated. Carlos (and producer Rachel Elkind) objected to the original cover and had it replaced, noting it "was a clownish, trivializing image of a mugging Bach, supposedly hearing some absurd sound from his earphones. That these were plugged into the input, not output, of a 914 Filter module, which in turn was connected to nothing, assured that silence is all that would have greeted Johann Sebastian's ears."
Carlos released Switched-On Bach 2000 in 1992 to celebrate the 25th anniversary of the original album's release. It is essentially a remake of the original LP — not a re-release — using state-of-the-art (as of 1992) digital synthesizers and computer-assisted recording. Although the CD contains the same track listing as the original, with the additional inclusion of a) a brief, introductory original composition styled as a birthday fanfare for the project and b) Bach's Toccata and Fugue in D minor, BWV 565 at the close of the album, the new digital synth sounds, in period tunings, are radically different in feeling, prompting some criticism from disappointed fans.
In 1999, Carlos released the Switched-On Boxed Set, a lavishly produced 4-CD boxset comprising the following albums in their original form:
- Switched-On Bach
- The Well-Tempered Synthesizer
- Switched-On Bach II
- Switched-On Brandenburgs (differs from its original 2-LP and 2-CD release by including only the remaining Brandenburg Concertos not heard on the previous three discs)
The albums have been remastered by Carlos and include some bonus tracks. The boxset also includes a 150 page booklet with photos, production notes, digital links to her website, etc.
