This has to be one of the most mind blowing, extensive, detailed documentaries of the history. I have always saturated myself in the knowledge of the artists, the styles and places that hip hop has provided because it is such a large part of my life. I would say I am a thourough historian in this genre of music because of my passion for it. I was delighted to learn things I had never known before and being able to see things I have known in a different light. I had always thought it was Kool Herc that invented scratching but it in fact was not, it was Grandwizard Theodore. I always thought that Public Enemy was the first group to do political rap, not so. KRS-One was doing it just a few years before, but PE took it too another level.
