Urban Alchemy/Gordon Matta-Clark The late New York-area artist who used entire blighted buildings as his sculptural material could not have found a more apt (temporary) home. The architectural stock Matta-Clark repurposed finds innumerable analogues beyond the Pulitzer's walls; each instance serves as a brief visual lesson in the aesthetics of simple dwelling spaces. Like archaeological strata, the layers of linoleum, plaster, wood beams, shingles, wallpaper and paint attest to the intricacy of the quotidian and the accretive elegance of all things driven by necessity. The message seems to be: Look closely and let nothing be taken for granted. Beyond the diffusions of daylight so scrupulously choreographed by the museum's celebrated architecture, siting this survey in St. Louis does a service to both artist and city. Matta-Clark was an innovator in the synthesis of architecture, activism and art — a catalyst of exactly the sort this town could use.
