Art for the walls of Denver’s main performing arts complex is put up on a first-come-first-served basis. Artists sign up and wait until their turn comes up. But the art is democratic, it’s almost nearly always bad, writes Kyle MacMillan. “It is only logical that what is shown on the walls of the Boettcher and Buell should be of the same caliber as the dance, music and theater presented on the stages of the two halls. Anything less demeans the performers who appear there, and it reflects badly on an otherwise vibrant local art scene and the city at large.”
