Kishio Suga first made Differentiated Order, a sculpture of paper and stone, in 1979. For his current show at Blum & Poe, he has remade it, placing a large, circular sheet of black paper over a constellation of gray stone blocks. Perfect rectangles cut into the paper reveal the stones holding it up, but the surface looks so smooth that it almost seems the gray of the stones has been painted on. Such subtle tricks are Suga’s forte. In the gallery’s foyer, a thin branch weighted down by concrete stands on the floor and arcs back to connect with one of three wooden shelves that Suga has attached to an all-yellow, wall-hanging canvas. Upstairs, grass protrudes from stacks of cinderblocks that stretch across most of the gallery space.
