Hopsins new album "Knock Madness" is clearly something for real rap fans. Hopsin produces all his own tracks and packs in almost every track an incredible lyrical depth. He is probably one of the few rappers that can still be described as "real", one has to look only times its Facebook Page. As much for its part commented and discussed fan questions and it also depends happy times with fans before and after his shows from. "Knock Madness" is musically again further developed than its already excellent predecessor album "Raw". It convinces with consistently great beats and varied rap parts of Marcus Hopsin where he up to all sorts of relationship problems treated topics of the hardness of the rap game. Best Track my opinion is "The Fiends Are Knocking" which somehow reminds me of "Nocturnal Rainbows" from "Raw".
