Angélique Kidjo lends her voice to the Occupy Wall Street movement with her acapella version of Tracy Chapman's "Talking About A Revolution." She is just one among the many musicians who have come out in support of the Occupy movements across the country and the world. Check out Talib Kweli freestyling it up down at the Wall Street occupation itself. And Russell Simmons and Kanye got down with them, too. For all the vids of the musicians and others supporting - check out our Occupy one-stop-shop here - where you can also learn how you can get involved, even if you can't get your (lazy? across the globe? tired? busy? injured?) ass down there.
