Global Citizen, the international advocacy organization behind the annual New York festival, is putting on a star-studded concert in Johannesburg, South Africa to raise money for various nonprofits and advocacy groups across the world.

The fest, known as “Mandela 100” to mark 100 years since Nelson Mandela’s birth , features performances from Beyoncé and JAY-Z, as well as a joint set from Pharrell and festival curator Chris Martin,  Kacey Musgraves, Ed Sheeran, Eddie Vedder, Usher, Wizkid, Femi Kuti, and more.

Rather than putting tickets on sale, the festival asks fans to earn tickets through advocacy and social justice work, as reported in Pitchfork.

Global Citizen is seeking to raise $1 billion in new commitments for causes such as “ending hunger and increasing access to good nutrition, ending neglected tropical diseases, reducing HIV transmission rates, ensuring every child receives a quality education, reforming and repealing sexist laws, providing funding for women’s health and family planning, and ensuring access to clean water and safe sanitation world wide.”
