This recording is a historical wonder, particularly valuable for putting the music of Ladysmith Black Mambazo in context. One of the obvious distinctions of mbube groups were who sang soprano parts in the absence of women. The earliest of the recordings is from 1932 and the history extends to 1967, ending with the song, "Umama Lo" by Ladysmith Mambazo which is a transcription of their first radio appearance. They didn't record their first album until six years later. The other most notable recording is the 1939 recording of "Mbube" by Solomon Linda's Original Evening Birds. This was the song which became "The Lion Sleeps Tonight" when western artists tried to phonetically recreate what they heard from the record. Oh well. Other notable groups are the King Star Brothers, Crocodiles and the Shooting Stars.
