2025 stock 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commissioned and briefly released, on August 7, 1967, by Capitol Records in the 4-track Stereo-Pak format only and then withdrawn due to a lawsuit from MGM Records.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 concrete pieces that combined elements from the original orchestral performance with elements of surf music and the spoken word. It was praised for its music and editing. The album's got all the offbeat, tripped-out qualities that you'd expect from late 60s Zappa – but at times, it's also got this tightness that's really amazing – almost as if Frank's showing the world that he can easily do the same things as the studio wizards of LA pop – but chooses to keep most of his efforts on the wrong side of the tracks! There's plenty of larger backings at points – handled by some of the cream of the crop of the LA studio and jazz scene – but other moments are pretty darn raw, and have a gritty, almost homemade sound collage feel
