In celebration of the opening of Light Years: Conceptual Art and the Photograph, 1964–1977, the Art Institute of Chicago will project Andy Warhol’s 1964 film Empire—a single, eight-hour-long nighttime take of the Empire State Building—from the museum’s Bluhm Family Terrace across Millennium Park to the upper stories of the Aon Center. Warhol’s work thus sets the stage for the artists featured in Light Years who redrew the boundaries of both photography and contemporary art. On view December 9 through December 10.
