Sooooooo rad. One of my hands-down all time favorite documenatary films. Watch it and be transported back to the early 80's. Very gritty, great soundtrack (and a killer narration by some old dude which is so out of place that it's dead perfect)
I think you can get it on Netflix.
BTW, I'm blissfully stuck in the 80's when it comes to rap/hip hop. All I need.
