Killer Mike recently stopped by the Tuff Cut Studios in Burbank, Calif. to meet up with the team over at Yours Truly. And while there, he walked over to the mic to spit the entirety of R.A.P. Music's massive second track, "Untitled." He promises that he'll kill it when he starts rapping and, sure enough, he does just that with El-P's brooding, intense production behind him. You can watch the performance above.
