Yo obviously cuz of location I can't tell you any US groups but here's some UK groups...

Dizzee Rascal and The Roll Deep Crew - Fuckin great MC there.. Most tracks are garage MCing so US cats prolly won't like it.

So Solid - As long as it ain't their poppier stuff (they have about 287 members) so thy have a wide variant of styles. So SOlid is practically all of South London - Asher D is prolly the best. And Megaman - yall US Cats migt like their non garage stuff.

57th Dynasty - Amazin - these cats are raw as fuck.

Met them at a show (for someone else) fore they brought their album out and I'm pretty good mates with the kid rapper in there now...

I'd say more but none of yall will check em out so...
