In a bold move that crosses analytic divides between medical anthropology, linguistic anthropology, and ethnomusicology, Steven Black explores connections between HIV/AIDS, medicine, music, faith and activism in South Africa. The analytic scope of Speech and Song at the Margins of Global Health is matched by its inspiring ethnographic depth. Charles Briggs, co-author of Making Health Public This ethnographically rich volume explores the remarkable case of a South African Zulu choir in Durban consisting of HIV sufferers who, as activists, negotiate social stigma and medical organizations through song, faith, comradeship and traditional language. Black's concepts of 'bio-speech community' and medical-semiotic 'transposition' provide an innovative theoretical framework. David Parkin, author of Anthropology Situated in the Contemporary World
