For over forty years, the Ladysmith Black Mambazo has been the voice of South African musical tradition around the world. Rock audiences were first introduced to the group when they collaborated with Paul Simon on his 1987 album, "Graceland." Ladysmith Black Mambazo's new album, "Songs from a Zulu Farm" celebrates their rich musical and cultural heritage. They join host Kerri Miller for a live in-studio performance.
