"Heinz Mack: From ZERO to Today, 1955–2014"

Coinciding with the Guggenheim's survey of the postwar ZERO group, this exhibition focuses on the work of the group's cofounder, collecting examples that span nearly 60 years. Mack's ongoing interest has been the exploration of light through various permutations of geometric abstraction based on a grid format. Starting with shallow, monochromatic reliefs that literally illustrated the play of light and shadow, he's since progressed to painted canvases taking a colorist approach to the same theme.
