Leigh Ledare once noted, “Any given image is underwritten by an ecology: by structures, interrelations, and circumstances.” Ledare is interested in relationships—or, more to the point, their simmering subtext. So he turns to social psychology and sociology. His video installation The Task, which sees his camera subtly disrupting a psychological group experiment, screens twice daily during this exhibition. Five Ledare assemblages are also on view. —E.C.
