So Youssou N'dour, Alpha Blondy, Magic System, etc. are receiving millions after performing at Bercy and Zenith ? Because of big sponsors like La Poste, ING, etc. financing their concerts and their own country renting the hall ? But artists like Koffi Olomide, JB Mpiana, Werrason and Papa Wemba receiving peanuts compared to Youssou N'dour & Alpha Blondy and their bands often spliting after performing there.
