Probably because Kinshasa is Werra-city. But at the same time I think that their contract with Bralima would function as a umbrella. Also the support from influent donors and bandleaders who were anti-werra. 3th generation artists (except Koffi) didn't had alot of influence anymore (Papa Wemba coming out from jail, Emeneya having a dip, etc.). But I think that Koffi would support them a little bit like he did to Alain Mpela behind the scene for a short time when Generation A started. Koffi Olomidé was immediatly accused for being behind Les Marquis-creation and Werra's clan claiming that he paid the guys money to leave while he had nothing to do with it, the problems of les marquis and werason being something that has his origins in 2000. It was especially from the moment that Koffi did a short interview with journalist Marius Muhunga through the phone that they accused him. The sentence "by werra losing his musicians, we will see what he will do now" made WMM-fanatics and even Werrason himself furious.
Being based in Kinshasa and find a label would have been a challenge. 2004 was the year that many bands, even big bandleaders like Koffi struggled to find a recordlabel. Some artists from then starting auto-production or co-production. Ferre himself explained in an interview that it was really hard for les Marquis to find a label and the few who were there all refused to produce them. Even late Simon Ndjonang first refusing but after a moment calling them back and making them later sign that famous 10-years slave-contract.
The thing that killed Dream Team of Guy Moller and Nouvelle Ecriture de l'an 2000 was that they hadn't enough support. Dream Team depended on Mambo de Panama and the public itself saw them as traitors for the way they left Emeneya just before Zentih. Next to that they suffered from serious attack from donors and bandleaders, etc. coming from Bandundu who all backed Emeneya. They were lucky that they were able to release their first EP because Guy Moller made a copy after finding out that their original producers was in reality a guy who was sent to kill their project by making their harddisk dissapear. The following project "Systeme ya ba Chinois" got not released because the same reasons and all guys returning back to Victoria one by one (except Sampaio who joined Nouvelle Ecriture way before and Guy Moller who stayed a solo).
Bendoson, Ramazani, Christian na Nzenze & Pompom Miyake failed with their project after a good start because there wasn't any support and them not having a sponsor. late Bob Masua who had to produce them being Wemba's brother in law and being attacked by Wemba-fanatics and donors in Europe which made him stop to fund the recordings. Bendo and his friends having to look for another producers but nobody wanting to produce them out of fear and Bendo's interviews against Viva only making it worser. After a few months they were broke, the guys already thinking (except Bendoson) thinking about a return to Papa Wemba until getting approached by Koffi Olomidé to join Quartier Latin (Pompom Miyake being the only one to refuse the offer).
