Documentary on hip hop's beginnings

I wanted to share this with whomever (Jackie?) is doing their paper on hip hop, because its a fascinating piece of media about Afrika Bambaataa and the Zulu Nation, Malcolm McClaren, DJ Kool Herc, b-boy culture, and the South Bronx. The beginning is weird, but you'll get an idea of how different hip hop was in the early 80's and late 70's and how it served the south Bronx community.
