Vinyl LP repressing. Cruising with Ruben & the Jets is the fourth studio album by the Mothers of Invention. Released on December 2, 1968 on Bizarre and Verve Records with distribution by MGM Records. As with the band’s previous three albums, it is a concept album, influenced by 1950s doo wop and rock and roll. The album’s concept deals with a fictitious Chicano doo wop band called Ruben & the Jets, represented by the cover illustration by Cal Schenkel, which depicts the Mothers of Invention as anthropomorphic dogs. It was conceived as part of a project called No Commercial Potential, which produced three other albums: Lumpy Gravy, We’re Only in It for the Money and Uncle Meat.
