yeah i am with you on what werra did for the maison mere musicians,but then once you chose to become a leader
its up to you to do the work,look at robinio he came with fire with his generiques then got too much into relying upon another artist it slowed him down somehow
but for the case of chai,if there is one singer who is known and respected by artists of koffi jb werra and co unanimously on his talent and fans aswell chai is not too far from that,his problem is that he does not fit other crucial criteria,looks dancing,its like eboa lotin aswell,another example is zulema most congolese fans know that zulema is or used to be the monster of impro in groups,but his looks and lack of dancing and never really nailing a starting lineup microphone stopped his progression
