David Hammons’s latest tour de force, at L&M Arts, hits you with the kick of a mule. Large, gorgeous abstract paintings are installed, then draped with torn and crumpled garbage bags, plastic tarps, or fabric. One aqua-silvery beauty has an armoire shoved up against it. You come away thinking about the desire to be a painter, the many forgotten or overlooked artists, ruins, dreams of greatness at a time in which we are unable to look on these dreams without irony or cynicism. This is not glib comment-art about art. This is dazzling dead-on honesty. An early lock for one of the ten best shows of the year.
