A stuffed goat on a platform, with a tire tutuing its waist; paneled Combines that could double as changing screens—Robert Rauschenberg seemed always to be creating for the stage, and very often was. For a decade beginning in the 1950s, the artist Robert Rauschenberg served as Merce Cunningham’s set, costume, and lighting designer. In 1979, he began collaborating with Trisha Brown— “as if he lived inside of me, or me inside of him,” the choreographer remembered. With the exhibition “Trisha Brown and Robert Rauschenberg: Glacial Decoy,” the Walker Art Center celebrates the fruit of this first collaboration, with all the accessories to performance—including Rauschenberg’s translucent pastel colorblock costumes and his gorgeously inky, oversized photographs that slide behind the dancers for Glacial Decoy’s duration: L.A. palm trees, a crane in calm water, the detailed detritus of American industry. —Apollinaire Scherr

Complementing the exhibition, on November 11, is Dancing with Bob: Rauschenberg, Brown and Cunningham Onstage. The Trisha Brown company performs Merce Cunningham’s Travelogue (1977) and Brown’s Set and Reset (1983), in which a scrim overhead broadcasts scraps of what is by now very old news as the dancers below do a disappearing act of their own.
