Afro-Synth! Even the name is rad.
Afro-Synth is a must-visit site for anyone interested in popular music from southern Africa. As Spoek Mathambo has mentioned, there was a lot of interesting stuff being put out in SA in the 1980s. A lot of it is super cheesy too of course (I mean it was the 80s after all) but tune your ear in the right direction and you can hear how the Township Tech thing and SA house music would have evolved from this kinda stuff. The best part of this site is that the curator, one Mr. DJ Okapi, has kindly compiled some remarkable mixtapes of the best of the era, mixing struggle songs with love songs that will have you swooning over civil disobedience in no time.
