The Amen Break

Okay okay, I couldn't resist grabbing this as well-- again via the Worldwide Cultural Gonzo Squad, an oddly captivating video on the Amen Break, a six-second-long drum loop from the b-side of a 1969 single which was taken up by early sample-based music and is now the basis for entire musical subgenres, as well as every advertisement soundtrack ever. Also interesting for its discussion of copyright law, and the fact that it's narrated by a surprisingly realistic electronic voice.
