This spring will see the release on DVD of a documentary film that dramatizes the degree to which we’re all in this troubled world together. The film uses music to make that point and the further one that music can help heal our differences. Its producer, Mark Johnson, took video and sound equipment around the world. He spent ten years filming musicians and singers in South Africa, Moscow, New Orleans, Tibet and scores of other places, then melding their work into Playing For Change: Peace Through Music. I have seen only this clip of the documentary and was moved by it.
