This is Spinal Tap

Mockumentary about the most legendary band that never existed. Rob Reiner's satire is an intelligent, biting commentary on the rock business and its myths. The film is said to have moved hardened professionals such as Tom Waits to tears over this supposedly true drama from the rock business and over the years has blossomed from an insider tip to the revered mother of all rock mockumentaries. Reiner succeeds in conveying both the groove of the rock business and its fundamental conflict, the conflict between art and commerce, with a myriad of apt, witty and biting details.
