Cool video with Jay-Z and 45 King discussing the making of "Hard Knock Life." I like how Jay says, "He just disappears for years." I don't know for sure, but I don't think that's the case. Dudes just sleep on the 45 King. Why? I'll never understand. After all, he is responsible for both Jay-Z and Eminem's most critically acclaimed single. BTW, for more video of 45 King cutting up 45's, go here.
