Renowned Brazilian brothers/collaborators Os Gemeos, known for their enormous street art murals featuring vivid colors and strange, yellow dudes, just opened a show at Boston’s ICA. Whilst the bros are in town, they’re finding up with two huge pieces that are beginning to appear like some of their greatest work but. If your grandmother nevertheless thinks that public art is a nuisance, then show her these gorgeous approach images. And if you’re on the east coast, a road trip could be in order just before the summer’s out. The show at ICA/Boston runs till November, 25.
