Music History Lesson

I don't know how better to describe this video so I'm taking the youtube explanation of it:

This fascinating, brilliant 20-minute video narrates the history of the "Amen Break," a six-second drum sample from the b-side of a chart-topping single from 1969. This sample was used extensively in early hiphop and sample-based music, and became the basis for drum-and-bass and jungle music -- a six-second clip that spawned several entire subcultures. Nate Harrison's 2004 video is a meditation on the ownership of culture, the nature of art and creativity, and the history of a remarkable music clip.
