The art and evolution of music recording is one of the 20th century's great untold stories. Executive Produced by legendary Beatles producer Sir George Martin, this eight-part series combines more than 150 original interviews with rare archival studio footage - and an extensive soundtrack featuring almost 300 songs - to explore the extraordinary impact of recorded music on our lives.

While the lead singers in rock, pop, and R&B are the ones who get the glory, knowledgeable music fans will tell you the backing vocalists often add the touches that make a performance truly memorable, and though many backup singers have the respect of their peers in the music business, they're all but unknown to the average listener.
