Global Citizen Festival 2015

Returning for a fourth year with another big bash in Central Park, Global Citizen allows you to earn your way in to catch a starry bill—Beyonce, Coldplay, Pearl Jam, Ed Sheeran—by performing civic-minded acts, with a goal of eliminating extreme poverty around the globe by 2030. (Or you can, you know, shell out big bucks for VIP tix.) Get started by visiting globalcitizen.org.
