"Art in the Streets," the landmark 2011 exhibition at the Geffen Contemporary at MOCA, was the first major U.S. museum survey of graffiti and street art. Spanning four major cities and featuring work from over 50 artists, "Art in the Streets" gave a big fat fine art stamp to the work that meant the most to Complex readers. You're nobody till somebody gives you a retrospective. The same turns out to be true for entire movements.
