your post has just made me realise something with us fans,i have very rarely,almost never seen anybody give any credit whatsoever to tata masela makaba bula about bcbg and maison mere,it seems so much that the group split to pave way to two solo careers
indeed they did not agree anymore artistically aswell because the solo ambitions were growing too much so they started "thinking" music their own way and not anymore that common thing with makaba as the mastermind
bcbg tried to maintain the wenge rhythm as it was in the beginning but as they quickly lost makaba and mbokaliya the rhythm started to change they just maintained a "easy" sebene tempo ,while maison mere when werra failed to get his friend ficarre to continue former wenge rhythm remembered japonais had in him apart from the wenge style the wild style of station japana so they created some sort of mix,which was taken to another level by flamme and also the fact maison mere was built on a aggressive context to prove a point(you'll notice the same "rage" in academia's sanction for example ) while bcbg started(too) sure of their strength continuing calmly on same tempo
yes i think werra always had in himself that taste for to pick talented musicians but was always in makaba's shadow in terms of developing them(and getting the credit for that) so knowing he'd remain quickly the only leader he knew he'd be able to fully have his touch on them musicians and fully get that credit
and today he is just continuing to do what he always had in himself,i remember at some wenge concerts he used to come along with jb before the concert they'd sit and watch street groups playing before them and werra was taking notes at times
jb on the other hand can also smell talent but he clearly wont be on your back all year long to bring absolute best out of you for your own good and for the good of the group,he'll teach you some stuff then let you adapt swiftly with no pressure
