A Pop pioneer who got his start painting billboards may not seem like the likeliest collaborator for a famous minimalist, but Donald Judd first entertained the idea of exhibiting James Rosenquist’s loud canvases at his estate back in the late ‘80s. It didn’t come to pass, though, until just this week, as Rosenquist became the first living artist to show at the Judd Foundation, the late artist’s former home and studio on Spring Street. Judd’s praise for Rosenquist stretches back the ‘60s, pointing to him in his reviews for the likes of Art in America as “one of the first-known of the so-called pop artists.” “I was amazed that he was reviewing me!” Rosenquist, now 82, recalled. Judd’s son Flavin actually came up with the idea to exhibit Rosenquist at 101 Spring Street, and he curated the show that opens tomorrow, which will be up on the ground floor until August. “It all has to go together,” he said of the works he chose; for instance, “Time Dust—Black Hole,” a massive 35-foot canvas that the artist likened to “a parking lot in space for junk,” stretches across the space’s main wall, across from two Judd-designed daybeds where visitors are welcome to settle in with titles from Judd’s Marfa library. Another selection, “Yellow Applause,” a mechanized pair of paintings of hands, even “claps,” though at this point, it’s a little shaky – after all, its machine has been running since 1966.
