I own an early LP of (pre Wendy) After Carlos came out as a
transgender woman in 1979, reissues of
Switched-On Bach amended the artist credit to reflect her name, as was the case with the rest of her discography up to that point: Wendy Carlos Switched on Bach (without the later 2000, of course). (October 1968)
Switched-On Bach features ten pieces by Bach available under the
public domain,
[2] performed by Carlos, with assistance from Folkman, on a
Moog synthesizer. Carlos worked closely with the Moog designer,
Robert Moog, testing his components and suggesting improvements. Most of the album was recorded in a rented studio apartment in which Carlos lived at 410 West End Avenue on the
West Side of
Manhattan in
New York City,
[3] using a custom-built
8-track recording machine constructed by Carlos from components built by
Ampex. The initial track created, however, the Invention in F major, was recorded in the spring of 1967 on a
Scully tape machine in Gotham Recording Studios at 2 West 46th Street, where Carlos had brought Moog equipment for a commercial project.
