Say what you want about jam kids; these folks know how to organize a show, bring together a crowd, and they actually dance for danceable bands instead of crossing their arms all aloof. A couple weeks ago, I saw Jimkata play to a packed house at Rochester's Dubland Underground: over the course of the show, the energetic crowd even went from being about 4% female to approximately 32%, which is pretty empirically dope considering the often bro-centricness of the venue. Combining electro-rock, pop, and a rare strain of jamtronica that doesn't cross the Cheesiness Threshold, the Ithaca-based quartet has been steadily infiltrating the East Coast jam scene and galvanizing an audience over the last few years. Their most recent record, Ghosts and Killers, is available from www.jimkata.com with a pay-what-you-can price tag, but it's really in a live setting that the group excels. The bass thumps, guitars sparkle, and despite his otherwise unobtrusive, guy-you-didn't-notice-at-the-college-house-party appearance, frontman Evan Friedell's compelling voice and lively presence makes him a commanding centerpiece for Jimkata's transcendent mix of sights and sounds. They don't really make it out this way that often, so be sure to check them out tonight at The Forvm (4224 Maple Rd, 8pm, $10) with Buffalo jamsters Aqueous.
