JANUARY 19

The Cavern Club in 1962. CBGB’s in 1977. Seattle in 1991. Flash points in popular culture after which everything changed. So if you are not at Monday night’s premiere screening of Jeff Krulik and John Heyn’s documentary, Neil Diamond Parking Lot, you will eternally hate yourself. Ten years after making their undisputed classic, Heavy Metal Parking Lot, the pair of filmmakers returned to the Cap Centre/USAir Arena to profile the pre-show rituals of another set of rabid music fans. Since HMPL is destined to be added to the Library of Congress’ National Film Registry, Krulik and Heyn will also screen Heavy Metal Parking Lot: The Lost Footage, which gives even more glimpses into the unbelievable world where Judas Priest rules. But what will make this evening a landmark event remembered for all time is the additional and rare presentation of Forestville Rocks, a cable-access concert by indefinable primal rocker Butch Willis and the Rocks. Krulik calls Forestville “an after-dinner mint, wherein people can drift in and out of the room and not have to feel like it’s polite to sit and watch the whole damn thing.” Oh, but you will want to watch the whole damn thing. In fact, you won’t be able to look away. Willis may or may not show tonight, depending on his “busy” career. Shown as part of the New Alaska Film Society film series at 9 p.m. at the Black Cat, 1831 14th St. NW. $5. (202) 667-7960. (Dave Nuttycombe)
