With almost no warning save for a humming sound and a sudden gust of air, Mississippi tenant farmer Ed Bush witnessed a meteorite plough into the earth one day in 1922, a terrifying and sudden event which Lorna Simpson recounts in 3-D lettering on the wall of her solo show at Hauser & Wirth Gallery. Nearby, painted and silkscreened fiberglass panels picture a surface pockmarked with bullet holes, another allusion to violence that can descend unexpectedly and without reason. In the main gallery, a series of 12-foot-tall canvases feature huge, meteor-like rocks that appear to hover in space, perhaps arrested in their descent but still exuding destructive potential that has, at least momentarily, been averted. (On view in Chelsea through Jan 11th. Note that gallery hours change during the holiday period).
