As we all know, the history of sampling in hip hop can go pretty deep. Here is a film about the people you "always heard but never heard of." In 1973, a politician, a gangster, a visionary, a football legend, and a murderer's path's intersected to birth the most unlikely source of music.
The documentary features interviews from Questlove, Afrika Bambaataa, and others.
Watch the trailer for Sample This above and gear up for what sounds like one hell of a ride.
