"With Nothingtoodoo, his first solo show at the Mary Boone Gallery, Mr. Koh gives his ascetic side full reign, to disconcerting effect. He is performing a kind of abject penance that is hard to dismiss, even if you may initially want to; it is too quiet, unsettling and self-effacing. It involves a fair amount of physical discomfort, if not downright suffering, and in its own way it too is hard to look at.
The show consists of Mr. Koh, dressed in white pajamalike clothes, slowly circling a beautiful cone-shaped pile of rocky solar salt — 8 feet high and 24 feet across — on his knees. Not his hands and knees, his knees. Staring straight ahead, his upper body motionless, he circumnavigates the salt almost nonstop during the gallery’s public hours — eight hours a day, five days a week — for four weeks. Occasionally he lies prostrate on the floor.
The unusually austere gallery and Mr. Koh’s self-contained concentration definitely create their own atmosphere.”
