The Beatles follows the explosive development of the young musicians who became a world phenomenon and who were responsible for a consistently innovative and truly ground-breaking body of music. The author examines why this music - created, at least initially, as ephemera - made history and has remained so uniquely durable. Drawing on his extensive research into studio out-takes, demos, unreleased recordings and broadcast performances, Kozinn reveals just how the tracks took shape and how the group's live performances came to change throughout the Beatles' touring years.
