“Hello Walls”

This show presents postmodern takes on the venerable practice of painting on a wall, an art form dating back thousands of years. The twist uniting the works here, however, is the idea of creating murals meant to be temporary, site-specific projects painted over at the end of the show. So go see these works (by a multigenerational cast that includes Bochner, Daniel Buren, Wangechi Mutu and Kara Walker, among others) while you still can.
