Has he become a muslim or is he is trying to look more West African?
I think it is the second, Nouvel Horizon has a huge appeal in West Africa and he is trying everything to take that audience, first the Fulani like Chorus in Moyini Mbote at 1:05
And now this.
A Muslim or any religious person would not try to sabotage another fellow Congolese for his own personal gain, making the new comers insult and belittle their ex boss.
