Perceptions. In a real sense, this show is a response to the Biennial of the Americas, which ran through the end of July; some exhibits, like this one, extend into September. Bobbi Walker, owner of Walker Fine Art, was disheartened that the Biennial had so little to do with art in Colorado, so she was moved to assemble this powerful group show highlighting local talent. Inside the gallery's entrance, there's an abstract sculpture by John Murphy made from found metal vessels welded together; it's a marvelous update of John Chamberlain's junk-car assemblages. Hanging from the ceiling is an exciting Sabin Aell installation referencing classic modernism that's made from billboard fragments and old and colorful telephone wires. Beyond is a multi-part floor installation that includes small aspen trees by Kim Ferrer. Around the corner are digital prints of plastic buildings, and a wall's worth of little plastic blobs on wires by Lauri Lynnxe Murphy. The tour de force in the show is the hyper-realistic figural group made of brown paper by Emma Hardy, though I do wish the heartbeat soundtrack had been left out. Through September 4 at Walker Fine Art, 300 West 11th Avenue, #A, 303-355-8955, www.walkerfineart.com. Reviewed August 26.
