The heroic subject of Robert Gordon’s It Came From Memphis isn’t Elvis but the bohemian rock ‘n’ roll subculture that was spawned in the mother city during the heady ’50s and is still thriving today. Legendary producer and musician Jim Dickinson and photographer William Eggleston are the spiritual elders of this eccentric brood, which numbers Alex Chilton, Tav Falco, and out-of-town kin like the Cramps, among many others. Gordon discusses his book and screens his compilation of banned and bootlegged Memphis madness, which includes such oddities as DJ Dewey Phillip’s home movies and wild concert footage of Dickinson’s Mud Boy and the Neutrons. At 7 p.m. at Borders, 1801 K St. NW. FREE. (202) 466-4999. (Eddie Dean)
