Is he still active as singer? Because I heard that he became an police officer in Cameroon. And what about the long announced album Conjugesion ?

 YEAH he went to finish formation for police(he was a policeman before being professional singer) then he returned and now is the only leader of universal zangul
 type oxygene conjugaison you'll find songs of that album with of course that rhythm most musicians of extra just wont abandon

Music wise his is he commercually di people are STILL aware of him or like every ex Extra's member Roga made everything to not making hin shine as a soloist?

where is Kila mbongo and what is he doing? is he still singing?
