I may be way late to this so forgive me, but I just discovered there's a nonprofit record label within the Smithsonian as part of the Center for Folklife & Cultural Heritage, and its amazing. They have a bunch of great curated albums and playlists, and sell vinyl represses. I found an album from 1976 by David Nzomo called "Gospel Songs From Kenya: Kikambo Hyms" and have been listening to it all week. There's also some weird fun ones like an album of frog sounds or city soundscapes.
