“What day did the lord create Spinal Tap and couldn’t he have rested on that day, too?”

High camp meets low class in the raucous irreverence and biting satire of This is Spinal Tap. The film eschews the pedestrian concerns of the uninitiated masses (that’s us) and beckons us into a gaudy and patently ungodly world of glitter, pleather, and heady self indulgence. Spinal Tap gives hair metal a new lease on life, raising the stakes with outlandish stage sets, surly attitudes, appropriated tartan, and a hermetic nod to Stonehenge.

The mockumentary, nay rockumentary, flaunts its own performative excess, donning its defiance with pride and reveling in its debauchery. This is theatrical kitsch at its most delightfully scathing. This is Spinal Tap caricatures fame, satirizing the psychology of celebrity and the plight of the has-been without descending into cynicism. The indulgent dialogues between the band members are a veritable echo chamber, where asinine nostalgia and delightfully inane soliloquys get played on repeat.

Here are 15 pieces of evidence that prove that Spinal Tap is the visual and sartorial revelation you need.
