Lumpy Gravy is the debut solo album by Frank Zappa, an album of orchestral, electric and concrete sound 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 is his third album overall: his previous releases had been under the name of his group, the Mothers of Invention. Produced simultaneously with We're Only in It for the Money, Zappa saw Lumpy Gravy as the second part of a conceptual continuity that later included his final album, Civilization Phaze III.
