Art Movie Night takes the form of a lawn party with desserts and a screening of the PBS Art21 series installment “Investigation,” a close look at the processes of Swiss modern artist Thomas Hirschhorn, whose public collaborations “resist exclusionary and elitist aesthetic criteria,” Mexican photographer Graciela Iturbide, who explores cultural environments through emotional portraiture and Brooklyn-based sculptor Leonardo Drew’s dramatic installations composed of new materials that he “intentionally subjects to processes of weathering, burning, oxidation and decay.”
