With their vast spectrum and geometric shapes, the untitled oil paintings in James Marshall’s “Overweight” at Irvine Contemporary are like secular stained-glass windows, with a touch of street flair. Marshall, who also goes by his street-art name, Dalek, grew famous for his graffiti, but fans expecting his “space monkey” tag will be disappointed—the artist only hints at the creature’s form in the architecture he depicts. Marshall worked with Takashi Murakami as a studio assistant in 2001, and his energetic and kaleidoscopic works, each a sort of space-age landscape, display Murakami’s influence in both shape and color. His work is clean, mathematical, and precise—comparisons to Sol LeWitt are apt—and despite a nearly flat depth of field, one gets the feeling of gazing into an endless landscape, and getting lost in it. The exhibition is on view from 11 a.m. to 6 p.m. Tuesday through Saturday, to Saturday, June 21, at Irvine Contemporary, 1412 14th St. NW. Free. (202) 332-8767.
