On July 23, 1968, Frank Zappa & The Mothers of Invention took over the Whisky a Go Go for an all-night affair. FZ recorded the entire evening with a view to creating an album project.

 

Although bits were released by Zappa over the years, a full live album never happened and the tapes sat in FZ's Vault for 55 years. Now all three sets by The Mothers are being issued - with 2024 mixes - on this 3-CD edition with notes by Joe Travers, Pamela Des Barres, and an interview by Ahmet Zappa with Alice Cooper.
