in this interview serge is talking about how he almost joined elparis only for werra advising him not to join because for him they did not a long future ahead,not taking him to 4X4 like he wanted as he was planning something one day
 and there he reveals that they were rehearsing at werra's house the "roots" of the kibuisa album along with bouro mpela alpatshino and ferre with the conception of burkina faso(now i understand why burkina said in one of his interviews in kin recently that it was super easy for him to record kibuisa because he already knew most songs even before split) and briefly reveals for example that  the vocal of werra in daddet was his or the one of coco madimba was alpa's
he tried to limit as much as possible though what he could reveal knowing that it might be badly received
and he also said that he was actually working in private with blaise bula before becoming private of werra full time and savanet depitsho aswell,and that the song shopping is majority from him but blaise never used his songs it seems

Wow, Werrason could have a better band there. I mean Serge Mabiala, alpatshino, Ferre Gola and Bouro Mpela. Now that is a choir that I could see work well. So unfortuante that these four men never got to be together alongside Werrason in Maison Mere.
