 Post Malone and Jelly Roll will take the stage for the annual Global Citizen Festival in New York City, set for September 28th. The gathering will be held, as always, on Central Park's Great Lawn, with free tickets available by using Global Citizen's app to take action towards one of the advocacy organization's key missions. Hugh Jackman is set to host with Coldplay's Chris Martin, a longtime friend of Global Citizen, and Jane Goodall due for special appearances. Additional performers are to be announced in the weeks to come.
