The companion to the funniest film ever made about rock bands. Rob Reiner's hilarious "rockumentary" about an aging British heavy-metal group has reached legendary status since its release in 1984. Largely ad-libbed by lead guitarist Nigel Tufnel (Christopher Guest), lead singer David St. Hubbins (Michael McKean), and bassist Derek Smalls (Harry Shearer)-as well as a succession of drummers whose careers were cut short by spontaneously combusting, drowning in somebody else's vomit, or other untimely deaths- This Is Spinal Tap chronicles the band's latest American tour in a cunning satire of rock and roll culture.
