Born in 1920, the pioneering Brazilian painter and sculptor Lygia Clark once said, “We do everything so automatically that we have forgotten the poignancy of smell, of physical anguish, of tactile sensations of all kinds.” Early on, Clark was a Constructivist and an important figure in the Neo-Concrete movement. But in the 1970s she became interested in sensory perception and psychology, and sought interaction between her art and the viewer. This survey explores her entire career. —Elena Clavarino
