The album brings together timeless talents, each with their own unique vocal styles - ranging from Paul McCartney, Bob Dylan and James Taylor, to Sting, Hozier, Sam Smith, Seal and Josh Groban. Country star Tim McGraw, and jazz influenced chanteuse Laufey, also lend their unique styles to their duets, and a powerful all-star trio, featuring Barbra joining forces with Mariah Carey and Ariana Grande, is also included on this album.
