At one end of David Zwirner Gallery’s vast white cube space hangs a detailed painting of tangled, leafless branches by Toba Khedoori; across the room is the artist’s painting of a grid of variously hued blue rectangles. In the juxtaposition of natural forms vs those that echo the built environment, Khedoori presents dichotomies of art practice: expressive freedom or impersonal rigidity. While most imagery in Khedoor’s show is centered at the middle of large sheets of wax-coated paper, one painting of tall grasses offers linear forms arranged to depict wildness, bridging the dynamic and measured in one small canvas. (On view in Chelsea through Oct 21st).
