All those videos video hadn't any choregrapher, because they are just following the dancesteps of the cri's. Each cri has his own dance. All dances are mostly created by streetbands in areas like Bandal, Ngaba, Kimbanseke, Ngiri-Ngiri, Masina, etc. or sometimes even coming from village, being an old dance that used to be danced by are ancestors. Many people just think that dances like Helicopter, Tchaku Libondas were created in the late 90s. But in reality they are recylced dances of the 70s who orginated from the Kongo-tribe, where they were dancing it in the village during funerals, weddings, birth, etc. and those who emigrated to Kinshasa bringing it with them. The same for many dances who orginate from the Mongo-tribe, who were later used in the 80s and 90s.Only the part of the female dancers in Generation Bercy and Ultimatum had an choregrapher. In Generation Bercy, it was the late dancer Monica Celeste who made those dances that Patience, Sandralina and Chouchou were dancing, creating also the dancesteps they used in the rumba's Babou and Logique. Koffi regretted her departure, because in a 5 months she spent in Quartier Latin, she contributed alot. In Ultimatum it was dancers Nono ba Diamants who brought those dancesteps. She stole those dancesteps from her master Mbuta Muntu Radja, where she used to dance before joining Quartier Latin (her ex'boyfriend Somono also came from there). They rehearshed on those dancesteps, but she decided to go back to Kinshasa before the clip got shooted. Mbuta Radja Kula was really furious at Koffi, when the videoclips came out, because it were his dancesteps and they danced it without his authorization (not knowing that his ex'dancer Nono brought it to Quartier Latin). Radja Kula created many dances in 80s and 90s, they were danced by all bands (Wenge, Zaiko, Quartier Latin, Big Stars, etc.).In Congolese music they rarely use choregraphers. Because every cri has already his own dance, that's a phenomenon that exist since the since 70s with Zaiko and Thu Zahina. They only use choregraphers for female dancers (having guys like Mao, Lambio Lambio, etc.) or when there are big events at Zenith, Bercy, Bercy or in Kinshasa at FIKIN, Cinemax (which don't exist anymore), Intercontinental.
