Thanks for the recommendations!

Regarding the history of the phenomenon, TBF labels like Habibi Funk and Awesome Tapes from Africa have been around for a while, and they're releasing actual regional music, including that from decades ago. Habibi Funk is from the mid-2010s, but ATfA is twenty years old currently. There's also stuff like ‘Cambodian Rocks’ from 1996 and ‘Saigon Rock & Soul’ from 2010, both with songs from the sixties-seventies.
