If you have ever listened to hip hop or drum n' bass, you've probably heard the "Amen break," a 6-second sample from a B-side to a Grammy Award winning single by the Winstons in 1969. This video is a documentary of sorts. The narrator is really monotonous, but the content itself is interesting as hell.
