"R.A.P. Music" is the latest album from Killer Mike featuring the always excellent production of El-P. The guy is a phenomenal rapper, and he's pissed. And some of that's been missing from hip-hop as a genre lately. Think Ice Cube 20 years ago and you're getting close. This one kind of came out of nowhere and bit me in the ass. Get it from Williams Street Records (a la Adult Swim) and listen to "Reagan" below. Not to pun, but it's killer.
