Before anyone controlled our base, before we ever watched someone else’s kid hallucinate on dentist-office meds, before that double rainbow went full-on, so vivid, across the sky, the original viral video was Heavy Metal Parking Lot. This was back when such epidemics spread way more slowly, and through a series of dudes, rather than via the Internet. You couldn’t share it on your Facewall, and you couldn’t watch it in the palm of your hand, but Jeff Krulik and John Heyn’s 1986 short — capturing the raucous, beer-swilling, acid-tripping, “they-should-roll-a-joint-that’s-so-big-it-goes-all-the-way-across-America” tailgating scene outside a Judas Priest concert in Largo, Maryland — was a thing of underground legend. And really, 25 years later, it still is. In a rare public screening, The Belcourt brings HMPL to Nashville to open up the Found Footage Fest, and believe this: Even though you can watch it on Hulu, it is way more metal to experience this thing with a crowd.
