Contributed by Margaret McCann / In two shows at Bookstein Projects, excess and essence complement one other from opposite ends of simplicity. Janice Redman’s “Rough Alchemy” in the side gallery presents mostly small, hand wrought sculptures that project vulnerability, earnestly offering themselves in all their imperfections to our subjective examination. In the main gallery, Diana Horowitz’s “Light is a Place” highlights objectivity in landscape paintings that broadcast optical truth from across the room despite their tiny size. In portraying distance, they keep their own, reticently holding the walls.
