The phrase “They Knew What They Wanted” poses countless questions, especially when placed as the title of a collaborative exhibition between four galleries across the city of San Francisco. As it turns out “They” are artists chosen by each gallery to curate a show comprised of artwork from the backrooms of all four galleries. Altman Siegel Gallery chose Los Angeles based photographer, Shannon Ebner to curate their portion of the show. She chose a series of thirteen random objects ranging from glasses of water to photographs to a baby incubator in an attempt to show that “reality is comprised of basic units.” The show at Altman Siegel is successfully disjointed with pieces that are singularly intriguing. Tom Otterness’s ‘Broken Humpty Dumpty’, a bronzed Humpty Dumpty situated on the floor, creates a vibrant dialog with the viewer because of its surroundings. Ebner knew what she wanted from the back rooms of these galleries, but you will have to look to Fraenkel Gallery, Ratio 3, and John Berggruen Gallery to see what their selected artists wanted.
