Marcus Jamal known as Hopsin a 33 year old rapper out of L.A. started off his music career with ruthless record the broke off from the Ruthless label due to differences between the label and him. So he went out on his own and started his second label Underground Prodigy. He put out 5 albums under that label and one of them albums is KNOCK MADNESS. I like the album project how they orderized the songs, just the hole arrangement of the album was right on. But there were some song that sounded a lot like the same as another song but in different words.
