An LP on the Disco Deal label recorded in France back in the 80's I would guess - I've had this album from Brick Lane market for many years now. Mostly laid back instrumental latin sounding guitars from Angola. Nothing to be found about him on the net although found a few recent records so he's obviously still around and making music.
This is what Wikipedia says about the music of Angola-
"The music of Angola has been shaped both by wider musical trends and by the political history of the country. In the 20th century, Angola has been wracked by violence and political instability. Its musicians have been oppressed by government forces, both during the period of Portuguese colonization and after independence. Angolan music also influenced Lusophone music in Brazil and Cuban music. The capital and largest city of Angola is Luanda, home to a diverse group of styles including Angolan merengue, kilapanda and semba, the last being a genre with roots intertwined with that of Brazilian samba music. Just off the coast of Luanda is Ilha do Cabo, home to an accordion and harmonica-based style of music called rebita. Compared to many of its neighbors in Southern Africa, as well as other Portuguese colonies (especially Cape Verde), Angola's music has had little international success. The first group to become known outside of Angola was Orquestra os Jovens do Prenda, who were most popular from the late 1960s to the early 1970s, and have continued sporadically performing and recording since. The big band included two trumpets, a saxophone, four guitars and a half-dozen percussion instruments. They played kizomba (a native style based around the marimba xylophone), using the four guitars to approximate the sound of the marimba, and quilapanga."
