"This Is Spinal Tap" shines a light on the self-contained universe of a metal band struggling to get back on the charts, including everything from its complicated history of ups and downs, gold albums, name changes and undersold concert dates, along with the full host of requisite groupies, promoters, hangers-on and historians, sessions, release events and those special behind-the-scenes moments that keep it all real.

Spinal Tap, England’s loudest and most punctual band, reunite following a 15-year hiatus for one final concert.

Spinal Tap is back in a whole new feature-length rockumentary. Go behind the scenes and find out where the somewhat-less-than-fab three are now -- and where it all began in Squatney, England. Also, catch up with director Marty DiBergi, ex-Polymer marketing whiz Artie Fufkin, and Jeanine, who now owns a shop specializing in itchy Irish clothing.
