Lumpy Gravy - Recording

Recording

Following the release of Freak Out!, the debut album of the rock band The Mothers of Invention, Capitol Records A&R representative Nick Venet commissioned an album of orchestral music composed by the Mothers of Invention's leader, Frank Zappa, a self-taught composer. Venet invested $40,000 in the album. Because Zappa's contract with Verve and MGM Records did not allow for him to perform on albums recorded for any other label, he could not play any instrument on the proposed album, and instead served as the conductor of an orchestra consisting of session musicians hired for the recording. Zappa states that "my contract did not preclude me from doing that. I wasn't signed as a conducter."

Lumpy Gravy was conceived as a short oratorio, written in eleven days. John Cage served as a major influence on the album. Zappa named the group assembled for the sessions the "Abnuceals Emuukha Electric Symphony Orchestra".

Percussionist Emil Richards recalled that he did not know who Zappa was and did not take him seriously as the recording sessions began, believing that Zappa was merely the guitarist for a rock band. However, upon meeting Zappa, who handed the musicians the scores for the pieces, which were dense, complex and varied in time signatures. Richards' close friend, guitarist Tommy Tedesco, was another member of the recording sessions. Tedesco mocked Zappa, believing that Zappa did not know what he was doing. The bassonist and bass clarinetist hired for the sessions refused to perform their parts, declaring them impossible to play. Zappa responded, "If I play your part, will you at least try it?" Zappa then played the notes for the musicians, who agreed to perform their assigned parts. By the end of the recording sessions, Richards and Tedesco became convinced of Zappa's talent, and became friends with the composer. Richards later performed on sessions which appeared on Zappa's album Läther.
