Switched-On Rock is an album of instrumental cover songs, popular songs from the mid-to-late-1960s, performed on the Moog modular synthesizer in an exaggerated electronic style. It was one of a spate of albums which capitalized on the success of 1968's Switched-On Bach by Wendy Carlos. Switched-On Rock was produced by Norman Dolph who also wrote the liner notes. Dolph worked in the studio with colleagues Kenny Ascher and Alan Foust; they billed themselves as the Moog Machine for this and one more project. The album reached number 170 on the Billboard Top 200.
