Contributed by Jonathan Stevenson / Despite the still breathtaking majesty of the physical world, human machinations are undermining its habitability. The United States is more starkly and toxically divided than it has been since the Civil War, and some Americans claim, contra Woody Guthrie, that “This Land” – the title of Leslie Wayne’s cogent new exhibition at Jack Shainman Gallery – was made only for them and not for other Americans. This existential double-whammy leaves artists with something of a conundrum: how to honor and present beauty robustly without seeming cluelessly disengaged. Wayne finds the sweet spot.
