in this interview there is soloist platini "plata" who claims he is the one who played in selfie,plata was the soloist of boguys bompema and joined quartier latin just after that bcbg and boguys vs koffi and kisindjora thing
him and jerry speer(who is stil in solo unlike title suggests)were group mates with dakumuda

There are different styles in the soloing on 13eme Apotre, i believe even Champion Kanda's work is on there. Glad to know that Plata played on Boguy's album,it explains why the animation from Boguy's album(ah Yesu) appeared on 13eme Apotre.
