The fifth annual Global Citizen Festival takes place on September 24th on New York's famed Great Lawn at Central Park. As we're now properly mid-summer (and it's almost August) (!!), the yearly festival has unveiled their line up.

This year's headliners happen to be a couple of the biggest names in pop/hip-hop. Rihanna and Kendrick Lamar are among top billed, performing alongside Major Lazer, Selena Gomez, Metallica, Usher, Ellie Goulding and more. You can check out the full list of performers in the flyer above.

For those not aware, Global Citizen Festival is a free concert that aims to have fans take certain social action and initiatives-- with a longterm goal of ridding the world of poverty. Tickets might be free but you still need to earn them. You can head to the Global Citizen Festival website here to find out how.
