A close-up view of the heavy metal scene in its heyday (maybe too close), Heavy Metal Parking Lot is an underground classic recorded on video in the parking lot of a Judas Priest concert at the Capitol Center in Largo, MD, in 1986. Director John Heyn wandered around the drunken parking lot scene and barely had to do anything other than hold up a microphone and aim the camera. Packs of plastered kids unfurled homemade Judas Priest banners, sang their favorite Judas Priest songs, played air guitar for the camera, and in general, made incredible asses of themselves. The interviews are pretty simplistic. They ask questions like, "Why are you here?" or "What do you guys think of Judas Priest?" So, the filmmakers were fortunate that the crowd that day exuded so much unbridled enthusiasm and were willing to completely lose it in front of the camera. Other than the interviews and images of fans, this short film features a couple of Judas Priest songs on its soundtrack and less than a minute of concert footage at the end to round out this nearly legendary, no-budget hit.
