Doug Aitken wasn’t the first artist to see the cinematic potential of the Hirshhorn’s donut exterior. Others, like Krzysztof Wodiczko in 1988, have used the Gordon Bunshaft–designed building as a surface for projected works. But it was Aitken’s “SONG 1”— touted as the world’s first large-scale, 360-degree convex-screen projection—that treated the Hirshhorn grounds like the drive-in movie theater it could’ve always been. With its celeb cameos—Devendra Banhart! Giant Tilda Swinton head!—and indie-rock doo-wop covers, “SONG 1” may have been more spectacle than satisfying art, but as spectacular art, it was exactly the picnic and make-out spot Washington needed last spring. Now that the museum knows how to make 11 digital projectors (and inward- and outward-facing speakers) do their thing, it ought to extend its National Mall–only medium to other artists. Maybe ones who’ll make something a little less soothing than “SONG 1”: I bet a Matthew Barney horrorscape would pair well with a picnic blanket and brie.
