On December 2, the musical duo will other artists such as Ed Sheeran, Chris Martin, Pharrell Williams, D’banj, Femi Kuti and others at the Mandela 100 Festival organized by Global Citizen network to put an end to “extreme poverty.”

Oprah Winfrey will deliver the keynote at this year’s event on teachings from the former South African president, per CNN.

“Nelson Mandela’s life story is a testament to the power of the human spirit and one man’s ability to change the world by standing up for what he believed in,” Oprah Winfrey told Global Citizen. “It is one of the great honors of my life to have spent so much time with him, and I look forward to celebrating his courageous life.”

Global Citizen has held a concert every year since 2012 with the goal to get the youth active in worldwide issues.
