Listen to MASIMBABELE by The Unknown Cases.
For me this is the quintessential Bumrocks track. I don't know if you know bumrocks.com, but it's a really great, long-lived music blog, which basically just posts a link to a song every day. No fuss, no muss. But the songs are consistently high quality, with a lot of proto-world music electro-dance obscurities. Plus lots of every other thing too! Hard to describe exactly, but after downloading dozens, if not hundreds of tracks there over the years, I feel like I know them well enough to judge. Seems like the blog is in remission currently, let's hope it comes back soon.
