A pretty epic collaboration piece is going down right now in NYC. After attending the opening of the PRISM group show, then hitting up Yosemite with Barry McGee, the twins have now started a huge mural with Futura in Chelsea. Os Gemeos is definitely on a roll after working with another legend, Blu, in Lisbon just a little while ago in May. Now, New York will have not one but two murals from the Brazilian duo.
