History of the Amen break
Here's a video history of the Amen break. It's an interesting story and then it turns into an anti-copyright rant at the end which I'm not feeling. I'm not sure how The Winstons all quitting music and getting nothing while countless artists and companies get rich using their recording is supposed to be some happy ending that everyone trying to make a living in music should be shooting for. "Hey kids, give up the copyright on your music and you too can bust out of the music business and wind up with a PHD in political science!"
Without some sort of success story for The Winstons I think all the example does is serve as a musician horror story: how you can make something that impacts millions of lives and still not be able to support yourself. Spooky!
