[The Conversation Africa] If Miriam Makeba is hailed as the South African vocalist of her generation who brilliantly embraced (and actually shaped) global music sounds, and Sathima Bea Benjamin as the experimenter who entranced the modern jazz scene in Europe and the US, then Ncediwe Sylvia Mdunyelwa joins that pantheon of late, great South African singers as the consummate vocal classicist. Known affectionately in her home city of Cape Town as "Mama Kaap", Mdunyelwa passed away on 25 August at the age of 74.
