Another moog album, "Electronic Hair Pieces", covered songs from the hippie-influenced musical, "Hair". The mod album cover art for "Electronic Hair Pieces" featured a model with a wired-up skull; liner notes were provided by Tom Smothers of the Smothers Brothers. Another album, "The Wozard of Iz", a psychedelic satire based on "The Wizard of Oz", also with words by Jacques Wilson, featured Bernie Krause providing environmental sound effects and Suzie Jane Hokom voicing Dorothy. Garson was quoted at the time: "An electronic composer utilises the synthesizer as a means of expression.. Of course he must remain master of the instrument and not vice versa, but given the unique vehicle, he has the medium in which, almost literally, the sky's the limit for his imagination."
