Black Steel is, well in my mind, the best Rap song of all-time, no one has nailed it so cold, hard and serious. In case you didn't know, the premise is, a dude gets a draft letter, he doesn't believe in his country and his country doesn't believe in him, so he dodges not really thinking too much of it, the government goes after him, they toss him in a cell, turns out it's a work-camp a la legal politically run new style slavery ring, so in the end he plans an escape, in which he participates in many violent acts due to being in jail's mental malaise, meaning the government took a seemingly normal person, crammed him in with a bunch of criminals, junkies and other dodgers, which eventually turned him into a cold blooded killer!! I realize the song is charged with the racial issues of the time, but I'm sure there were multicultural draft dodgers dealing with the same problem, giving Black Steel universal theme.
P.S. I don't really like or know too much about hip hop!
