Deep in the mines of South Africa, isicathamiya (is-cot-a-ME-Ya) was born. The distinct musical genre developed from miners trying to pass the six-day work week with song. Using this style, Ladysmith Black Mambazo acts as both a globally recognized a capella group and preservers of South African tradition. Known for their rich combination of history and crystalline sound, their dynamic harmonizing is one of the musical underpinnings of Paul Simon's multi-platinum album Graceland. The group will perform selections from their Grammy award-winning album, Live: Singing for Peace Around the World at the Mahaiwe Performing Arts Center in Great Barrington on February 6 and will host a panel an hour before show time to discuss life in South Africa.
