Spinal Tap are a fictional British rock band from the cult classic mockumentary This Is Spinal Tap (1984). Known for their over-the-top stage antics, absurd lyrics, and satirical take on rock ’n’ roll excess, the band became a pop culture icon. Blurring the line between parody and reality, Spinal Tap perfectly captures the chaos, ego, and humour of life in a heavy metal band proving that sometimes, rock really does go up to eleven.
