Contributed by Mary Jones / Katy Crowe returns to as-is.la with “Lunar Shift,” a superb second show of eleven lively and resonant abstract paintings. All are oil on linen works completed within the last year, six of them 52 x 42 inches and five 24 x 18 inches. A strikingly linear installation puts two opposing walls of the gallery into play, with the paintings equally spaced. The formality of the presentation underscores the dichotomy between window and object inherent in all paintings but Crowe’s especially, and brings out buoyant rhythms from painting to painting.
