As the world mourns the passing of cultural icon Nelson Mandela, so too is the music industry.

During the course of his life, the anti-apartheid activist formed strong ties with Pop culture to broaden the reach of his core message – unity.

One of the many artists touched by Mandela is R&B pioneer R. Kelly.

Taking to the stage on The Arsenio Hall Show last night, the crooner performed a haunting tribute to the South African president titled ‘Soldier’s Heart’ – a song he penned for civil rights leader, and one he performed for Mandela at his house.

Watch Kelly soar after the jump…
