This was released in 1971 and reached No 31 in Britain. It features drumming by 25 members of the Ingoma people in Burundi recorded in 1967, with a guitar and piano arrangement by French record producer Michel Bernholc, using the pseudonym Mike Steïphenson. You can see more detail here. https://en.wikipedia.org/wiki/Burundi_Black
I would have preferred the drumming by itself.
