There's no denying "human beatbox" Yuri Lane's mad skills or freakish repertoire of rhythms and sounds. And his best bit--a heavy-beats-and-harmonica blues fusion--is a real barn burner. But if 90 minutes of his guy-from-Police Academy meets the Fat Boys shtick strikes you as a recipe for mime-level annoyance too, no amount of chops is gonna change your mind. Lane's hip-hop tour of Chicago isn't aided by the Frommer's-style list of neighborhoods visited, a faint story driven by a superficial take on gentrification, or the collection of patly precise, staggeringly unimaginative neighborhood types he and writer-director Rachel Havrelock have devised. Through 10/29: Thu-Sat 8 PM, Sun 7 PM. Viaduct Theater, 3111 N. Western, 773-296-6024. $10-$20; industry nights through 9/25.
