Here is an excerpt from http://www.playingforchange.com:
"Playing for Change is a multimedia movement created to inspire, connect, and bring peace to the world through music. The idea for this project arose from a common belief that music has the power to break down boundaries and overcome distances between people. No matter whether people come from different geographic, political, economic, spiritual or ideological backgrounds, music has the universal power to transcend and unite us as one human race. And with this truth firmly fixed in our minds, we set out to share it with the world."
How great is that? Playing for change, now that is something I can believe in.
