Creating these videos motivated us to form the Playing For Change Band—a tangible, traveling representation of our mission, featuring musicians met along our journey, and establish the Playing For Change Foundation—a separate 501(c)3 nonprofit organization dedicated to building music and art schools for children around the world.
Through these efforts we aim to create hope and inspiration for the future of our planet.
