Reggae, and in particular roots reggae is still massively popular across Africa.
Tiken Jah Fakoly is currently criss-crossing Europe (new dates are still being added to the current one to keep up with demand).

Alpha Blondy is one of the pioneers.

What's interesting is the degree to which these artists walk the talk. Ivory Coast has been in civil war for years. Both of them get up and say what they think is right, at the risk of being shot. Fakoly is currently exiled in Mali.
Other artists include Fadal Dey and Serge Kassy.
