Contributed by Adam Simon / The five abstract paintings in Medrie MacPhee’s “The Repair,” at Tibor de Nagy, have just enough indications of figure/ground and observed reality to evoke landscape, interior space, aerial view, blueprint. What also connects these paintings to the physical world, as we perceive it, are minor shifts of line, contour, or color that activate the surface and keep the paintings from being flat. While the paintings are large, all but one measuring 64 x 84 inches, somehow the small gallery doesn’t feel crowded.
