I'm not from Quebec but I've lived in MTL for a long time (hence I'm quite familiar with the artists you mentioned). To me Sans Pression, YK, KC, Connaisseur that was a new era... emcees started incorporating a more traditional Quebec accent/slang (Joual in some instances) in their delivery and lyrics. That was the start of some call "Rap Queb", a style which still exists today. Although I like Dubmatique's first two albums a lot, I find them very close to the French (from France) aesthetic of the time... Soulful, quasi boom bap beats with "clean" flows so to speak. In a (relatively) recent interview with CKUT community radio, DJ Choice mentions the strong influence of MC Solaar on Disoul. Muzion, their body of work is a whole nother story (more eclectic, multilingual French/Creole/English approach).
@Fade KCLMNOP... oh that guy. He had a great 1st album if you ask me, not the strongest spitter but he could hold his own. But I guess his antics/issues outside of the music industry got the best of him and he stopped being productive.
