Rubber Soul has been credited by the band's media agency as "marking a pivotal moment in The Beatles' evolution". All of the new Rubber Soul formats feature the album's new stereo mix, sourced directly from the original four-track master tapes. Across the Super Deluxe collections, fans can hear 24 early session recordings, including 20 previously unreleased takes and three previously unreleased home demos including Little Girl, a previously unheard John Lennon song outline never before released. The 4CD and 5LP Super Deluxe editions are accompanied by an 88-page hardbound book featuring a new written introduction by Paul McCartney, and a foreword compiled from John Lennon's own words. Rubber Soul will be available in standard 1CD and 1LP editions, 2CD and 2LP Deluxe, and 4CD and 5LP Super Deluxe editions, as well as Blu-ray, alongside limited-edition orange vinyl and D2C exclusive Zoetrope vinyl editions.
