"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, one of England's loudest bands, makes another final reunion. After all, it's rock'n'roll. This is actually a demo reel that Rob Reiner created to get financing for his 1984 film "This Is Spinal Tap."

The now estranged bandmates of Spinal Tap are forced to reunite for one final concert, hoping it will solidify their place in the pantheon of rock 'n' roll.

The concept of Back from the Dead is that Spinal Tap has reunited in honor of the 25th anniversary of This Is Spinal Tap, and have launched an "unwigged and unplugged" tour. The album is packaged with a DVD featuring commentary on each of the album's tracks.

Shot at Stonehenge, the mysterious landmark that we now know must have been erected thousands of years ago purely to serve as the setting for the last act of Spinal Tap. The ultimate meeting of rock mythology and cinematic scale. An iconic band performing at one of the world’s most legendary landmarks and turned up to eleven.

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.
