Listening to the music I just couldn't believe this was another of the many anonymous bands from Congo. The cassette sleeve offers very little information, other than that the cassette was made in Kericho, Kenya.
A further search revealed more information about Orchestre Fauvette. Apparently the orchestre is from the east of Congo and was founded in the 1960s. Prominent member of the orchestra was Ndala Kasheba, a singer/guitarist, who later moved on to lead the Safari Sound Orchestra. There is a promotional video (here) in which he talks briefly about his life and in which he is seen playing with singer King Kiki (both are in the photo on the right, 'borrowed' from this informative article by Banning Eyre). The latter also was a member of Fauvette.
Ndala Kasheba died of a heart attack in November 2004 (see this article).
When fighting broke out in Katanga in 1967 while Fauvette was touring the eastern provinces of Congo, they decided to continue their tour outside of Congo. First they went to Bujumbura (Burundi) and from there to Kigoma (Tanzania). In 1969 they moved to Dar Es Salaam, where they were welcomed by Western Jazz, a very popular band at the time. Fauvette soon set up a base there and recorded a few tracks at the studio of Radio Tanzania Dar Es Salaam. One of these is the track "Mama Nakupenda" ("Mama I love you"), which is on this cassette.
In 1970 King Kiki, who -like Ndala Kasheba- grew up in Likasi, joined the orchestra. Two years later the band left Dar Es Salaam and changed its name into Safari Nkoy. After a short period in Bujumbura they returned to (then) Zaïre, where in 1974 Kiki left the orchestra.
So I think it is safe to assume that these remarkable recordings, released on the rare Stranger of the 70s label, were made in Tanzania.
