Text excerpt from the disc cover: The recordings published on these two discs were made among Mbwela, Nkhangala and Chokwe-speaking communities in the province of Kwandu-Kuvangu, south-east Angola, from August to December 1965. These are probably the first recordings made in this area. During this period, it was possible to work in remote and hitherto ethnographically largely unknown village communities on the upper Kwitu River, as well as on the Kwanavale and its small tributaries in the then Circunscrções Longa and Cuito-Cuanavale. The research trip in 1965 was financed by the then Junta de Investigações do Ultramar, Lisboa. The analysis of the material was continued in the context of official invitations to the author by the Secretaria de Estado da Cultura of the People's Republic of Angola in August/September 1979, as well as in 1981 with Angolan informants.
