text: U2 guitarist The Edge said in the documentary It Might Get Loud that when he first saw Spinal Tap, "I didn't laugh: I wept," because it summed up what a brainless swamp big-label rock music had become.
  In a 2023 interview Chris Frantz of Talking Heads said "we watched Spinal Tap and I thought, ohh, I can never take myself seriously again."
  Use of Spinal Tap as a descriptive term
  It became a common insult for a pretentious band to be told they were funnier than Spinal Tap. As George Lynch put it, the more seriously a band took themselves, the more they resembled Spinal Tap. After seeing a 1986 performance by metal band Venom, singer Henry Rollins compared them to Spinal Tap. In their respective Behind the Music episodes, Quiet Riot's Rudy Sarzo and Ratt's Robbin Crosby compared their own bands to Spinal Tap to some extent. For example, as a parallel to the "Shit Sandwich" incident, Quiet Riot's fourth album Condition Critical was given the two-word review of "Prognosis: Terminal" by J. D. Considine in Musician magazine. His review of the short-lived band GTR's eponymous debut LP in the same magazine was "SHT". R.E.M.'s Mike Mills described the band's early tours as "very Spinal Tap", citing, among other things, they had played at a United States Air Force base.
