Lumpy Gravy (1967 album)

Lumpy Gravy, also known as Lumpy Gravy (Primordial), is the recalled original debut solo album by Frank Zappa. It is an entirely orchestral recording written by Zappa and performed by a group of session players he dubbed the Abnuceals Emuukha Electric Symphony Orchestra. Zappa conducted the orchestra but did not perform on the album. It was commissioned and briefly released, on August 7, 1967, by Capitol Records in the 4-track Stereo-Pak format only and then withdrawn due to a lawsuit from MGM Records. MGM claimed that the album violated Zappa's contract with their subsidiary, Verve Records, and the album was recalled.

In 1968, a second version of the album was released by Verve on May 13, 1968, which consisted of two musique concrète pieces that combined elements from the original orchestral performance with aspects of surf music and spoken word. The original 1967 album was reissued in 2018 under the title Lumpy Gravy (Primordial).
