Ladysmith Black Mambazo is a South African male choral group singing in the local vocal styles of isicathamiya and mbube. They became known internationally after singing with American Paul Simon on his 1986 album Graceland. They have since won multiple awards, including five Grammy Awards the fifth of which they dedicated to the late former South African President Nelson Mandela.

Isicathamiya is a singing style that originated from the Zulu people, a South African ethnic group. In European understanding, a cappella is also used to describe this form of singing.
