The Mothers of Invention entered TTG Studios to record "Help, I'm a Rock"—among other tracks for the Freak Out! album—after record producer Tom Wilson signed the group to MGM Records under the incorrect assumption that they were a traditional blues ensemble. As a testament to its absurdity, Zappa explained "Help, I'm a Rock" was created spontaneously as "just a thing that spewed out. What was happening was what was in the air that night".[4] For the composition's unusual droning background sounds, the band encompassed screams, duck calls, alien beeps and chatter, tribal chants, and erotic moans that simulated a female orgasm.[5] In the liner notes to Freak Out!, Zappa wrote the tongue-in-cheek statement: "'Help, I'm a Rock' is dedicated to Elvis Presley. Note the interesting formal structure and the stunning four-part harmony toward the end". He concludes his comments on the song by jokingly remarking about "the obvious lack of commercial potential. Ho hum".[6]
"Help, I'm a Rock" is a three part suite consisting of: "Okay to Tap Dance", "In Memoriam Edgar Varese" and "It Can't Happen Here". In the first pressing of Freak Out!, the song was credited simply as "Help, I'm a Rock". However, as Freak Out! reissues and compilation albums were made available, the third part, "It Can't Happen Here", has been commonly listed as a separate track. In concert, the composition was typically mixed with other band songs, most regularly "Hungry Freaks Daddy".[6] One music critic notes "Long term, the psychedelic workout had plenty of commercial appeal, with Zappa’s bands playing it throughout the master’s career. 'Help, I’m a Rock' became one of the many catch phrases attached to Zappa over his career".[4]
A section of "Help, I'm a Rock" called "Third Movement: It Can't Happen Here" was also featured as the B-side of the DJ-only "How Can I Be Such a Fool?" single. With a running time of nearly nine minutes, "Help, I'm a Rock" remains one of the Mothers of Invention's most lengthy and experimental pieces in their catalogue.[7]
In 1967, psychedelic rock group the West Coast Pop Art Experimental Band recorded the song on their second album Part One.[8]Richie Unterberger described the rendition as a concept that "flung them into freakier pastures", with its style being "emulated convincingly on the group original '1906', an apt soundtrack to a bummer acid trip with its constant spoken refrain, 'I don't feel well'".[8]
