This documentary is a portrait of popular South African group Ladysmith Black Mambazo and their founder Joseph Shabalala. Their innovative and silky harmonies provide the backdrop to this film, which features Paul Simon.

Ladysmith Black Mambazo rose to prominence amidst the conflict in their country and took their Isicathamiya music to an international audience. The genre was born a century ago in the mines of South Africa where Black migrant workers, far from their homes and families, sang songs early on Sunday mornings. They called themselves "tip toe guys", referring to the dance steps choreographed so as to not disturb the camp security guards. These entertainments eventually turned into contests, with the winning group receiving a goat. The music they sang evolved with Western influences.

The film tells a moving story about a sensitive performing company of singers whose roots are in Zulu music and who have created a style of their own. Some of the songs of Ladysmith Black Mambazo are humorous; many of the hybrids they sing protest about apartheid. The group played a major role in Paul Simon's hugely successful Graceland album, and Simon is interviewed during the film.

But the real fascination here is the music itself and the men who sing it, led by Joseph Shabalala, whose dream it was to tour with his company - and who finds his songs in his dreams.
