Carrie Underwood will headline the Global Citizen Festival on Sept. 27 on the Great Lawn of New York's Central Park with Jay Z, No Doubt, The Roots and Tiësto.
The festival, which will air live on MSNBC, serves to highlight the issues surrounding global poverty, a cause very close to Underwood's heart.
"I believe we all have the ability to make our world a better place," the singer said in a release. "Positive change is possible when we work together, and this festival is a hopeful opportunity for all of us to help see an end to extreme poverty."
Last month, the singer and her husband, hockey player Mike Fisher, embarked on a mission trip to Haiti with Danita's Children, an organization that cares for orphaned and impoverished children – just one example of her dedication to giving back.
In total, 48,000 free tickets to the star-studded Central Park concert will be given out to "global citizens" who take action to earn their admission. By signing petitions, emailing world leaders and sharing content on their social networks, fans will become active participants in campaigning for positive change and earn points that can be used to enter the drawing for tickets.
