Stewart explores the power music has to bond people in ways that are fundamental to our evolution and existence. His travels take him from the Southern German cave where a 40,000 year old bone flute was discovered to the modern day mass singalong of New York’s Choir! Choir! Choir! Along the way he gets to play with a Memphis marching band, join a song circle led by Bobby McFerrin and deconstruct the sexiness of Relax with its producer Trevor Horn. He also discusses the art of song-writing with his old colleague Sting and learns how to create dance floor unity with International star DJ Honey Dijon.
