In April 1975 Zappa had a one-sided demo acetate disc cut at Kendun Recorders in Burbank, California.

The album is a notable entry in Zappa's discography, because it was the last to feature a majority of his early 1970s band, which appeared on Over-Nite Sensation (1973), Apostrophe (') (1974), Roxy & Elsewhere (1974), and One Size Fits All (1975).

Napoleon Murphy Brock's vocals are featured both on the sprawling "Advance Romance" as well as on the three-part harmonies of "Carolina Hard-Core Ecstasy".

Captain Beefheart, in his only tour with Zappa's band, delivers vocals and harmonica on several tracks, including his two short prose readings "Sam with the Showing Scalp Flat Top" and "Man with the Woman Head".

Perhaps because there's a blues avatar up top, the jazzy music has a soulful integrity, and though it's embarrassing to hear the Captain deliver Frankie's latest pervo exploitations, the rest of the songs are funnier because he's singing them.
