A billboard for Heineken Light, situated on Lafayette and Great Jones in downtown New York, announced "This billboard is occasionally perfect." As billboards go, it was adequate -- big and well lit, but far from perfect. But on August 17th, it suddenly lived up to its billing, as the sign was transformed into a stage for an impromptu street concert by indie stalwarts TV on the Radio. Stay tuned because the billboard, part of ad agency Wieden+Kennedy's "Occasionally Perfect" campaign for Heineken Light, just may become perfect once again. Check out a video of the event after the jump.
