Over the weekend, El-P and Killer Mike announced via their respective Twitter accounts that we would finally be hearing the first track from their upcoming R.A.P. Music project on Monday. Well, it's Monday, and here we are, shaking the crust out of our eyes and getting hit by a flurry of hi-hats, grimy synths, and that "real G-shit." "Big Beast" finds Mike sharing bars with fellow Southern stalwarts Bun B and T.I. while shit-kicking newcomer Trouble handles the hook. The best part about all this is the fact that Mike sounds like KRS-One at his most furious with a hint of molasses. You can stream the massive track below.
