9. 'This is Spinal Tap' (1984)
Everybody sing along now: "Stonehenge, where a man is a man/And the children dance to the pipes of Pan." No movie ever captured the absurdity of the rock life like this one. And it couldn't have been done without getting the musical details right. But Christopher Guest, Michael McKean and Harry Shearer turn the Tap into a real band, from brain-dead Seventies boogie like "Big Bottom" to epic art-metal like "Stonehenge." Tonight they're gonna rock you tonight!
