This weekend, the fourth annual Montauk Music Festival kicked off summer 2013 without skipping a beat. From May 16-19, indie musicians took to local venues for the volunteer-run, grassroots live music festival. Among the festival's featured musicians were folk, pop, rock, and hip hop artists. If you're looking to relive the weekend's most Instagram-worthy moments (or if you didn't make it out East), we've rounded up some of the festival's finest photos, from sand to stage!
