WHAT "Larry Rivers: Collaborations and Appropriations" presents 11 large-scale relief paintings in which the late Hamptons artist "borrowed" from works of other famous artists. The exhibit also features eight collaborative drawings from the "Stones" series of lithographs created with poet Frank O'Hara, plus a pair of experimental films by Rudy Burckhardt that focuses on Rivers in a performance ensemble with other painters and writers, including Jane Freilicker and Fairfield Porter. Guest curator Helen Harrison of the Stony Brook University-affiliated Pollock-Krasner House and Study Center, writes in the show's catalog: "Perhaps because of his background as a professional jazz musician, Larry Rivers was predisposed to creative collaboration and appropriation. Neither practice was common in the late 1940s and early 1950s when Rivers was making the art scene in New York City."
