Lumpy Gravy is a 1968 solo album by Frank Zappa, written by Zappa and performed by a group of session players he dubbed the Abnuceals Emuukha Electric Symphony Orchestra & Chorus. Zappa conducted the orchestra but did not perform on the album. It is his fourth album overall: his previous releases had been under the name of his group, the Mothers of Invention.

Frank Vincent Zappa was an American musician, composer, and bandleader. In a career spanning more than 30 years, Zappa composed rock, pop, jazz, jazz fusion, orchestral and musique concrète works; he also produced almost all of the 60-plus albums that he released with his band the Mothers of Invention and as a solo artist. His work is characterized by nonconformity, improvisation sound experimentation, musical virtuosity and satire of American culture. Zappa also directed feature-length films and music videos, and designed album covers. He is considered one of the most innovative and stylistically diverse musicians of his generation.
