watch this 20 minute documentary about a 6 second drum loop

Seriously, it seems like it should be absurd that someone could make a 20 minute documentary about a 6 second sound clip but it's really interesting.

from the youtube summary:

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.
