In a city known for its idiosyncratic tastes in art—including not just one but two giant blue animal sculptures—local visionary Jim Green fits right in, not least for the fact that you can’t actually see his work. What you can do is hear it: take a ride (or two) on his Laughing Escalator at the Colorado Convention Center; wash your hands in his Singing Sinks at the Denver Art Museum; pace the intersection of 15th and Curtis until you hear the whistles and hoofbeats of his Soundwalk rising up from the pavement grates.

Green’s recorded installations defamiliarize the mundane environment through which we usually move so thoughtlessly, startling us into laughter—and his exhibition at the Museum of Contemporary Art, continuing through January 3, 2010, is no different, centering as it does on whoopee cushions.
