Bono, Manu Chao, Stephan Marley and Tinariwen are just some of the musicians who have joined Playing for Change, a multimedia phenomenon that unites musicians from around the world. It dates back to 2004, when Grammy-winning producer Mark Johnson promoted a musical journey to discover buskers worldwide and combine their voices. Since then, the project has continued to grow, they've created a foundation and built music schools. With millions of fans around the world, Playing for Change has become a worldwide hit. Classics like 'Stand By Me' (with over 50 million views on YouTube), 'Gimme Shelter', and '(Sitting on) the Dock of the Bay' spread a message of peace and solidarity.
