Among the seven Star Power shows that inaugurated the new Museum of Contemporary Art/Denver last fall, David Altmejd is one of the few that are still open. A young Canadian artist, Altmejd covered the walls of the Family of Natasha Congdon Large Works Gallery with sheets of mirror, then created a series of anthropomorphic figures clad in mirrors as well. All that reflective material made the eponymous installation nothing short of an eye-dazzler. Selected by MCA curator and director Cydney Payton, this magical work was hands-down the best pick for the opening of the new building.
