I become sad if I think about Olivier Mopepe 'aka Sinistre". He was one of the most promising rappers back in the days. He rapped on JB Mpiana's song Bye Bye Julie.
He was the figurehead of rap-group Bana Kin, which had Youssoupha, Mike Evian, etc. I remember Koffi Olomide saying in an intereview in Kinshasa when they released their album Tendence, that that kind of music would never succeed in Kinshasa or Paris. but now 15 years later we have Naza, Keblack, Dadju, etc. Some have even more succes than the leaders in Kinshasa, since that the younger generation is prefer that king of music, then rumba/ndombolo.
