Not much of an african music fan really, but played with a couple of Kenyan musicians* for 6 years, and my ex-girlfriend was/is into some decent afrobeat bands:
Apagya Show band. They combined afrobeat and funk in a unique wonderful way. Very cool. Fela Kuti of
course. Orkestra Poly-Ritmo is interesting, still touring too. Tinarouen if you're feeling like smoking something but don't have anything available.
*(Note that "playing with Kenyans" involved mostly playing really decent Police covers... but there was some African/Soca/Reggae/Afrobeat music in there too
)
