Uncle Meat is the fifth studio album by the Mothers of Invention, released as a double album in 1969. Uncle Meat was originally developed as a part of No Commercial Potential, a project which spawned three other albums sharing a conceptual connection: We're Only in It for the Money, Lumpy Gravy and Cruising with Ruben & the Jets. The album also served as a soundtrack album to a proposed science fiction film which would not be completed, though a direct-to-video film containing test footage from the project was released by Frank Zappa in 1987. The music is diverse in style, drawing from orchestral, jazz, blues and rock music. Uncle Meat was a commercial success upon release, and has been highly acclaimed for its innovative recording and editing techniques, including experiments in manipulation of tape speed and overdubbing, and its diverse sound. Background Frank Zappa, who had been interested in film since high school, decided to develop a film vehicle for the Mothers of Invention, titled Uncle Meat. The proposed film would combine elements of science fiction and road stories inspired by the band's sexual escapades. Subsequently, Zappa began working on a project called No Commercial Potential, which eventually became the albums We're Only in It for the Money, Lumpy Gravy, Cruising with Ruben & the Jets and Uncle Meat. Zappa stated, "It's all one album. All the material in the albums is organically related and if I had all the master tapes and I could take a razor blade and cut them apart and put it together again in a different order it still would make one piece of music you can listen to. Then I could take that razor blade and cut it apart and reassemble it a different way, and it still would make sense. I could do this twenty ways. The material is definitely related." According to artist Cal Schenkel, "I started working on the story of Ruben and the Jets that is connected with the Uncle Meat story, which is this old guy turns this teenage band into these dog snout people ... We started that before it actually became Ruben and the Jets. That came out of my love for comics and that style, the anthropomorphic animals, but also it was part of a running story line." Recording For the recording sessions, Zappa worked at Apostolic Studios in Manhattan employing an unusual and innovative 12-track
