Retrospectives are typically hushed and reverent affairs, but this one—The Hotness: A Sort of Retrospective—includes painter Joe Park's sketches, scribbled jokes, student IDs, lamps he thought would change the world, collected Art School Confidential comics, evaluations by his students ("irrelevant and boring"), a bucket of water representing a 1983 performance that went terribly wrong, a drawing of his grandmother's house in Korea, and oh, well, yeah—some paintings. (Cornish Main Gallery, 1000 Lenora St, first floor, 726-5142. Noon–5 pm, free.)
