Hello,

Firstly, please don't mention the likes of Eminem or whatever because I'm looking for underground stuff, and not an artist who occasionally makes a dark song.What I'm looking for is hip-hop groups with gritty stuff... stuff with beats that has a dark atmosphere, lyrics that can be interpreted as morbid (can be overtly gorey or something like occult lyrics). They supposedly call it "horrocore hip-hop" or in recent times, "death rap" thanks to Necro. I love real hip-hop, but don't know too many artists who do dark-oriented music other than the likes of whack stuff like ICP (Insane Clown Posse, which even then their music is mediocre and don't have good flow; plus their stuff isn't really hip-hop.) 

Please help.

I didn't find the right solution from the Internet.
