I was also for years wondering who he was and asking myself why they didn't hire a woman to do that. But later on someone explained to me that it was actually maitre kembo. he's a professional dancer and was behind the choreography of the singers and female dancers for olympia, bercy & stade des martyrs. he did a great job for helping jb mpiana out for olympia, after the work late lambio lambio did in kinshasa for jb mpiana's zenith with anya star & his daughter ya yoyo.
shows done in paris by congolese artists after already having performed at a mythic hall in the same tour, are often not at the same level like the first one. i think that it impressed jb alot with him inviting him again to work for bercy.
from 2:33 min
him talking about recruiting dancers for jb's bercy and attacking a bandleader (i think koffi). i also praises his results of bercy, which made me wonder if he collaborated with koffi for bercy. because the way koffi's dancers danced at bercy was not the same like koffi's dancers normally danced the years before.
