Detroit guy, has done a lot of work with fellow Detroit producer/artist Black Milk. Guy is a genius. He's currently re-doing all of Nas's Illmatic on his own version called Elmatic. Not sure what to think since he's messing with a classic, but I think he can pull it off.
My favorite song of his
YouTube - [Europass] Elzhi f. Royce Da 5'9" - Motown 25
From his new CD [produced by Black Milk]
