Stevie Wonder, Kings of Leon, John Mayer and Alicia Keys will perform at the second annual Global Citizen Festival in New York City’s Central Park on Saturday, September 28. Like last year’s event, the festival will be free to those who educate themselves and spread awareness about a number of issues related to extreme poverty, like access to education, health care, women’s equality and more.

Those that are interested in attending the Global Citizen Festival must sign up on the event’s website before earning “points” through various actions like watching videos and sharing information. Those that acquire 8 points will be entered into a drawing for free tickets to the event. 27,000 two-person passes will given away.

In addition to the free tickets there will also be a small number of VIP tickets available for purchase through Ticketmaster, with exclusive offers for Citi cardholders.

Last year’s inaugural Global Citizen Festival featured performances by Neil Young & Crazy Horse, The Foo Fighters, The Black Keys, Band of Horses and K’Naan. The event raised $1.3 billion in pledged donations.
