Contributed by Sharon Butler / “Paul Feeley: The Shape of Things” is Garth Greenan Gallery’s fourth solo exhibition for the painter, who died in 1966. But it is the first to ask – and answer – what happened when Feeley, known for re-introducing geometry to post-war abstraction, grew tired of his signature style. This show at last gives proper attention to Feeley’s drive to move beyond the flatness of the canvases he had been producing for years.
