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commissioned and briefly released, on August 7, 1967, by Capitol Records in the 4-track Stereo-Pak format only and then withdrawn due to a lawsuit from MGM Records.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.

Absolutely Free is the second album by American rock band the Mothers of Invention, released on May 26, 1967, by Verve Records. Much like their 1966 debut Freak Out!, the album is a display of complex musical composition with political and social satire.
