From Bill Moyers Journal:
Bill Moyers sits down with Mark Johnson, the producer of a remarkable documentary about the simple but transformative power of music: PLAYING FOR CHANGE: PEACE THROUGH MUSIC. The film brings together musicians from around the world — blues singers in a waterlogged New Orleans, chamber groups in Moscow, a South African choir — to collaborate on songs familiar and new, in the effort to foster a new, greater understanding of our commonality.
Johnson traveled around the globe and recorded tracks for such classics as "Stand By Me" and Bob Marley's "One World" — creating a new mix in which essentially the performers are all performing together — worlds apart. Often recording with just battery-powered equipment, Johnson found musicians on street corners or in small clubs and they would in turn gather their friends and colleagues — in all, they recorded over 100 musicians from Tibet to Zimbabwe.
