Highlights and hidden secrets of the Walker’s contemporary art collections are presented in a lively sequence of rotations that unfold throughout the exhibition’s run. Inspired by the idea of the event horizon, a term that describes the edge of observable space, this exhibition threads together major themes and developments in contemporary art, while showcasing works in the context of the events that produced them. In changing over time, it reflects the many voices, perspectives, and programs advanced by the Walker over the past half-century, while acknowledging the continual evolution of art collections as works are added to the mix.
