most of wemba's old and recent albums(from 2000 to now) are written by him,for example the hit " six millions ya ba soucis"
then you have for example proces mambika of alain mpela,pacte divin of seguin maniata, djodjo ngonda of ficarré/werrason which were actually very songs from the 80s in teh group select musica where he was a singer
then kinshasa of jb,bana lunda of jb,many other songs given to jb yet to be released,in short he mainly collaborated with jb and wemba in this century but i know some of werra's temoignage songs are his aswell but not sure which ones
