Anyone else heard this yet? I have some friends up in Michigan so I keep on top of the Subterraneous crew. I just got my copy of S.O.N.O.G.R.A.M. in the mail, and i'm giving it my first listen. I'm pretty sure this guy has won hip-hop - He just beat the game. Some of the cleanest flows I've heard in years, no bling, no disrespect to women, no drugs, none of that... just beautiful rhymes over amazing beats.
There are some samples here:
