Os Gemeos — “the twins,” in Portuguese — is the nom de plume of the twin Brazilian artists Gustavo and Otavio Pandolfo (b. 1974) of São Paulo, Brazil. Their work borrows the idioms of outsider and folk art in a style heavily influenced by the one-time graffiti artist Barry McGee. And though, like Mr. McGee, they might once have been artists of the street, their gallery-sized installation at Deitch Projects, “Too Far Too Close,” suggests they have since become artists of the rec room.
