Directors Mark Johnson and Jonathan Walls inspiring tribute to the unifying power of music. With a spirit of peace and openness the two roamed across four continents for a year, recording various musicians at work in order to combine their distant voices into one global song. Johnson and Walls use split-screen editing, Super 8 footage, and moving performances of traditional music -- from the freedom fighters of South Africa playing the songs that helped topple apartheid to the Zuni of New Mexico performing ancient songs of religious devotion. Along the way, the musicians interviewed continually convey the idea that music is a tool to promote peace. This paean to humanity will have music lovers dancing in their seats.
