This is one of the most awesome things I've ever seen! People all over the world playing music together and the proceeds creating programs that are life-changers - In Africa, in Asia in South America, impoverished kids are learning and coming togehter through music. All because of one guy's idea. Little ideas have the HUGE power to change peoples' lives.
Check out the website at Playing for Change for more great videos, and to see the programs they're building. You can buy a child a drum, a flute, or purchase CDs for yourself. Totally awesome.
