Conner (1933–2008) is among the most important postwar artists you’ve probably never heard of. A pioneer of the West Coast scene and an early practitioner of found-object assemblage, he delved into rise of consumerist culture and fears of nuclear armageddon during the height of the Cold War. His work encompasses painting painting, sculpture, photography, performance and film. With respect to the last, his 1958 classic, A Movie, employed rapid-edit montages of appropriated TV commercials and movie footage put to an musical soundtrack; the darkly ironic result was startlingly ahead of it time. This show—the artist’s first monographic museum exhibition in New York, the first large survey of his work in 16 years and the first complete retrospective of his 50-year career—brings together over 250 examples of his groundbreaking work.
