I discovered this guy the other day. Apparently he has a new album getting ready to drop soon, so I checked out his previous drop, Bastard. He's of the hip-hop variety, sounds akin to MF DOOM and maybe early Eminem. His lyrics are vulgar and at times he sounds almost psychotic, but he's one of those guys who, unlike a lot of the mainstream rappers, raps with the brain and not with her dick. The video for one of his newer tracks, Yonkers, is getting a lot of recognition and attention for obvious reasons, heres the vid if you wanna check it out.
