Artpace opens New Works: 11.1, exhibits from the International Artist-in-Residence program, with an artists’ dialogue this Thursday night with E.V. Day, Kelly Richardson, and Devon Dikeou. Day, known for Bride Fight (right), her installation of giant exploding, dueling wedding gowns, has revisited feminine conflict in a roiling cat fight between two saber-toothed tiger skeletons hung by high tension wires from the ceiling at Artpace. Bones bedecked with silver leaf are caught in deadly embrace — or is it play? Canadian Kelly Richardson recently filmed at Uncertain, on the edge of Caddo Lake, the largest cypress swamp in the world. The computer-manipulated result is a panorama of moss-hung trees with ribbons of light that play over water like will-o’-the-wisps on acid. The 3-channel video pulls the viewer into a world that seems irradiated — an unfortunately timely reminder of ongoing nuclear crisis in Japan. And Dikeou, who runs zingmagazine in Austin, discovered a hotel lobby in Buenos Aires with a wall of plaques honoring famous jazzmen. Missing from the collection was her friend Sonny Simmons, a Bay Area horn man who played with Eric Dolphy and is still a monster on alto. Her install plays on the SA tradition of altars, giving Sonny his due. Free, opening reception 6-8:30pm, artists’ dialogue 7pm, March 24, 445 N Main, (210) 212-4900, artpace.org. Exhibits on view until May 22.
