Abstract-expressionist painting has miraculously held on despite the onslaught in the last decade of "new media," a field that includes installation, performance, video and digital. These forms were supposed to make painting look out of date, but, as Wet Paint proves, that's not what happened. The exhibit, which is open through April 10, showcases three artists covering new ground by riffing on classic ideas. And that's a national trend, as the show also proves, because the three artists live in different big cities across the country: Jeffrey Keith is from Denver, John Himmelfarb comes from Chicago, and Michael Rubin hails from New York.
