Mark Johnson is the founder of "Playing for Change"

Mark Johnson is the founder of "Playing for Change", an organization dedicated to uniting people across the globe through music. His inspiration came from seeing two monks performing in the Boston subway, and the crowds of people mesmerized - willing to miss their train to see these two men perform music. That image fermented in the back in his mind as he moved to Los Angeles, but it took a run-in with a street guitarist singing "Stand By Me" for the idea of Playing for Change to be rammed home. First, Mark made an award-winning documentary, then he started an organization to promote peace and unity through music worldwide.
