Vinyl LP repressing. 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. 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commissioned and briefly released, on August 7, 1967, by Capitol Records in the 4-track Stereo-Pak format only and then withdrawn due to a lawsuit from MGM Records.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. In 1968 it was reedited and reissued by MGM's Verve Records on May 13, 1968. It consisted of two musique concrète pieces that combined elements from the original orchestral performance with elements of surf music and the spoken word. It was praised for it's music and editing.
