he talks briefly about his own steps in various street groups but he could not make it on big group level and says its when he was in one of his last street groups that his brother heritier joined bcbg and was living at jb's house (sharing room with kibens)
funnily enough their mother did not even figure out him pontiack was singing in various groups already but she noticed for heritier quickly as he literally disappeared from home
jb wanted heritier to finish high school which he would have done in 1999/2000 and their mother was against him doing music because he was really intelligent at school but pontiack tried his best to convince her that he can combine both especially seeing how many people have loads of diplomas in drc but have no jb and he told her that so many people would love to be in heritier's position,living at home of a big star like jb and being presented on tv by him saying "this young guy is the future" and even papy kalombo who is now with fally used to say to him "your brother is a very lucky kid"
so she went at jb's home and it happened that she is somehow related to jb's family so they talked and agreed that he'd stay there but then one guy who was from same area as heritier and a fan of wenge's knew he was living with jb and went and took him to werra's house and heritier was a bit intimidated but also did not want to move away from bcbg since jb was one of his idols and werra proposed him to replace michael tshendu in the role of the youngest member of the group and live with him and heritier explained him that he had to go back home and take his clothes and so on and when him pontiack figured out what happened he was upset at him and he returned in bcbg but werra sent somebody again later on(while bcbg went to zenith olympia tour) to get heritier and on the way to werra's house  they meet a group of fans and heritier noticed some faces he saw at bcbg concerts so he got scared that they'll report to bcbg that it was seen with maison mere people seemingly heading to werra's house so if he goes to bcbg again he will not be accepted which is why he accepted totally to join maison mere and funnily enough he was tested neither in bcbg nor in maison mere  so he was a really lucky guy
he says singing is a talent in their family and it happened at home that they'd sing him heritier their sister and their mother
his interview is quite interesting but very long

No wonder Papa Cheri has a soft spot for him. So Heritier never completed High School after joining Maison Mere?

no,he actually failed one year in the transition from bcbg to maison mere when he started  having too much desire to become a professional musician then  succeeded in 2001 and from then his mother completely accepted him having a career

 he did reveal something interesting so nsone apparently(and quite likely given yanki's lives) sent papa eyenga to spy at rehearsals supposed to be wata's while it was the ones of his brother
heritier really wanted his brother to have a career aswell he did another feat with him before d de d and tried to get him some donors but then he did not have as much hunger as his younger brother so his musicians joined other groups
