Three 6 Mafia.
Now, they done sold out, sorda. They down to 2 members (Paul and Juicy, the producers). But they still producin the best beats, to me atleast, for their artists (Lil Wyte, Chrome, Frayser Boy, Project Pat (legend).
Their old shit from 95 to 2003, is the best rap music ive heard.
Their "music" is just amazing to me. I know they rap about stuff that "great" emcees dont really rap about. They rap and rapped about drugs, violence, robbery, demonic shit back in the day, and just real hardcore shit. But their beats were just so amazing to me, and still are, better back then tho, but their beats, their flow, their chemistry just sounded so good. Lord Infamous (no longer with them) is one of the most underrated emcee's ever, hes amazing. And they are the darkest rap group ive ever heard. 8 years of GREAT music (95-03).
I love dark rap, and 3 6 was the Kings of that. Their eerie, mystic, crunk ass beats.
I listen to Hypnotize Minds every day. I cant stop listenin to them. Instead of putting one of my other 250 plus rap CDs in, i put in 3 6 or Project Pat or Lil Wyte in because I cant help it.
With that being said, Tech N9ne still my fav Emcee of all time!!!
