"This group show, curated with an elastic intelligence by Alison Gingeras, may focus on monotone art works but it's far from monotonous. Carnality reigns in Betty Tompkins's painting of a couple in flagrante delicto, lending a hard-core edge to the tumbling folds of Robert Morris's felt sculpture. a salon-style hanging in one room runds the gamut from an 1815 swatch of wallpaper to an ecstatic little crowd scene painted this year by Jeni spota. Minimalist canvases by Brice Marden and Agnes Martin strike a contemplative mood, which explodes in a devious installation in the bathroom by Bjarne Melgaard. Through Jan. 14. (Luxembourg & Dayan, 64 E. 77th St. 212 452 4646)."
