In a bittersweet farewell performance, Martha Friedman is closing the doors of the venerable Andrea Rosen Gallery. Going forward, the revered dealer will focus on dealing dead artists’ work instead. “Dancing around Things” feels like old-fashioned switchboard operators gone mad. Wearing paint splattered studio aprons, two artists on either side of a metal sheet in turn either ram dangerously sharp objects into perforated holes or force pre-greased rubber tubes into the cavities. The result is an erotic, violent but skilful demonstration of female force and impels a contemplation of the violations of the female body. At Andrea Rosen through March 11.
