It reminds me of something Billy woods and the Super Cron Flight Brothers would listen to. I agree with the mood thing. I imagine some of this stuff would sound crazy coming out of somebody's car.
That second video sounds wild. The guy can flow, but that hook is sooo wack to these ears. I loved the 1st video, it kind of reminded me of Dead Prez for some reason. That 3rd one is weird as well. His voice reminds me of RZA's sometimes. I'll look into these guys some more, that's for sure.
