In 2012, Philip Glass journeyed into the mountains of Mexico to interact with the Wixarika people. Glass's passion to unravel the mystery of what music really is has been present throughout his entire career. He has expressed this passion through his travels around the world engaging with musicians of different ethnic and cultural backgrounds and creating new music with them. In Glass's the Concert of the Sixth Sun, the composer's collaboration with the Wixarika allows US a glimpse of their indigenous world of mystery and spiritual beauty. Guitarist Roberto Carillo Coco and violinist Daniel Medina de la Rosa are joined by the composer at the piano.
