You’ve likely seen the work of Gustavo and Otavio Pandolfo, the Brazilian twin artists better known as Osgemeos (or Os Gemeos). Sure, maybe you haven’t seen their work on buildings, but you’ve seen their output in art books or museums or on designer fashions. Their large-scale pieces, a teenage style of graffiti, is incredibly inviting—the kind of stuff you’d want to show a budding young artist. That might be why the Hirshhorn, the “hip” Smithsonian with a reality show on MTV that aired following last season’s RuPaul’s Drag Race, is giving them an entire floor for more than a year. If you’re trying to attract the same, slightly younger crowd that came out to the recent Laurie Anderson and Yayoi Kusama exhibitions, it’s a good idea to work with a couple of guys who went from spray painters making “illegal” art to art gallery darlings. Osgemeos: Endless Story opens May 18 and runs through July 6, 2025, at the Hirshhorn Museum and Sculpture Garden. hirshhorn.si.edu. Free. —Brandon Wetherbee
