Nelson Mandela’s 91st birthday will include more than cake, as rapper Lil Kim and ‘80s pop songstress Cyndi Lauper take the stage together to help celebrate the occasion during a concert to honor the former South African president. The three-hour event, which will take place at 8 p.m. July 18 at Radio City Music Hall, will feature what organizers labeled as “special collaborations” between performers.

In addition to Lil Kim and Lauper, Black Eyed Peas member will.i.am will perform with Jesse McCartney at Mandela Day: a 46664 Celebration, while Alicia Keys and Angelique Kidjo share their time on stage.

Soul music queen Aretha Franklin and Josh Groban will also take to the stage in a collaborative performance. According to event organizers, the Mandela Day celebration will serve as a global call to action for people to recognize their individual power to make an imprint and help change the world around them for the better.
