Here's two rappers I'm interested in. A word of warning: this will offend your retinas and somewhat squeamish occipitals
One is trying to rhyme like eminem (he's not terrible, but I don't know if he's real or if its another marketing schtick.) He's sort of punk-rap horrorcore, but not really
The next is a guy who, at the moment, I have a lot of respect for. He doesn't use gimmicks, just hard verse layin straight bass bombs. (from odd future)
