"Lumens & Currents: Elizabeth Chiles and John Swanger." For several years, artists Elizabeth Chiles and John Swanger pursued a thoughtful dialogue about the way their individual art-making practices complemented each other. Now, the pair debuts their latest paintings and, in Chiles’ case, photo-based work that celebrate luminosity, ethereality and the practice of close looking. 11 a.m. to 6 p.m. Thursday-Saturday, noon to 5 p.m. Sunday through Jan. 15. 2213 E. Cesar Chavez St. 512-826-5334,
