The Back2Black festival, a pioneer in the global appreciation of the black culture in Brazil, happening in the old Leopoldina train station in Rio de Janeiro, and bringing together concerts, debates, exhibitions and artistic interventions in four different spaces. For the 2011 edition, OSGEMEOS were responsible for the art direction of the event. The brothers developed the whole visual design for this edition, and made a huge installation on the roof of the Leopoldina Station, hanging about 200 inflatable balls with the design of humam faces, two meters in diameter each, in front of the main stage. They also gave color and designs to the trains of the station, in partnership with other artists, that during the festival became an installation filled with music, lights and mirrors. "The festival is a celebration of rhythm, the sound, the social and economic awareness, colors and styles of a new and pop world", says Julia Otero, one of the founders of the festival.
