Didace le Prof & Felly Tyson used to play the rhythm guitar on Magie and on V12 & Noblesse Oblige it was shared between Popolipo, Lebou, Felly & Koffi himself.
Do Akongo didn't play rhythm because he was always left behind Kinshasa, if they came to Europe to record Kofi's solo albums. He was lucky that Pas de Faux Pas was recorded in Brazzaville. For Magie i don't know, because 80% also recorded in Brazza.
I think that Koffi was leaving Do Akongo behind, because he thought that he would staying in Europe. Because he was from the 1st QL-Generation (Yoto Delta Force, Fofo Le Collegien, Toussaint, Vieux Veron, Djunafa, Mascot de Katalas, etc.), who where threaten Koffi to leave Quartier Latin due to getting a to low salary.
