San Antonio’s premier art incubator features rotating shows, displaying the work of three artists selected by a guest curator for two-month residencies: One artist must be from Texas, one from anywhere else in the United States, and one from anywhere else in the world. The result has been a fascinating mélange, with everything from twists on the traditional to cutting-edge conceptual. It’s a very stimulating art space, with lecture series by the artists as well as public forums to discuss the work.
