Last fall, the first Global Citizen Festival kicked off in Central Park with headliners Neil Young, the Foo Fighters, the Black Keys, Band of Horses, John Legend and K’Naan. The event, which took place on the Great Lawn, attracted more than 60,000 concertgoers and raised more than $1.3 billion in funding to fight worldwide poverty.

This September, the Global Citizen Fest will head back to Central Park, this time, with Stevie Wonder, John Mayer, Kings of Leon and Alicia Keys as headliners. The artists are playing with pay to support the fight against poverty.

“These four headlining artists are willing to play for free because they believe this generation wants to see the end of extreme poverty,” said Hugh Evans, co-founder and CEO of Global Poverty Project, one of the event’s organizers.

“We’re happy to take part in an amazing organization’s show that brings awareness to such an important global issue,” Kings of Leon said in a statement.

“What the Global Poverty Project and its Global Citizen movement have accomplished in just five years is really inspiring,” wrote John Mayer. “Their mission to end extreme poverty is one that we can all agree on, all support. I’m excited to be part of this year’s program alongside musicians I admire and working to end extreme poverty within a generation.”

Last year, the festival was timed to line up with the meeting of the UN General Assembly Meeting to put pressure on the world leaders and raise awareness of the issue of global poverty. Once again, the festival will be coinciding with the meeting of the UN General Assembly.

If you want to get into this year’s festival, the only way to gain admission is to take action against poverty. Once you take a certain amount of actions to support the cause, you are entered into a lottery to obtain the approximately 54,000 tickets available for the event.

“This year, we’re focusing on four key issues for maximum impact—education, women’s equality, health and global partnership—all of which are interrelated,” Evans said. The plan is to use technology to spread the word even more. “We’re exploring making the festival truly global by having live sites around the world broadcasting the event and local artists performing,” he said.

The 2013 Global Citizen Festival will take place on Sept. 28 in New York’s Central Park. For more information, check out the Gloal Citizen Festival website.
