Yeah Yeah Yeahs

Chicago's Grant Park becomes the center of the musical universe this weekend (Aug. 7-9), as Lollapalooza sets up shop on eight stages that will feature over 120 acts over the course of the festival's three days. Metromix is on hand to capture as much of the action as our tireless photographers and writers can endure.
