When you push a broom, you move forward, collecting the dirt and debris underneath and making room for a renewed surface. If you are a careless cleaner, the act of cleaning becomes an exercise in distribution. Ed Clark is such a cleaner. Pushing the ideas of abstract expressionism forward through relentless experimentations with materials, color and form, Clark has been instrumental in building on the foundations of Pollock and quietly shaping ways in which we now view gestural abstraction. By taking the broom to many lofty AB-Ex concepts, Clark exposed the subversive elitism of action painting, showed new approaches to materiality by fusing impasto and translucency, and helped pioneer the possibilities of the shaped canvas. That he has been widely left out of the art historical discourse of post war abstraction is an oversight that a current survey at Mnuchin Gallery seeks to address. The exhibition demonstrates that Clark is leaving behind a legacy of daring and innovate work – one that is at once perceptive and brainy – and one that leaves future generations of artists a bedrock to build on. At Mnuchin Gallery through October 20.
