The entire Beatles back catalogue has been digitally re-mastered for the first time and will be released worldwide on September 9th.

Each CD will come packaged with album art replicated from the original UK releases, as well as expanded booklets containing both original and newly written liner notes and rare photos.

An engineering team at Abbey Road Studios in London have worked for four years to re-master the records, using state-of-the-art recording technology alongside vintage equipment.

The collection comprises all 12 Beatles albums in stereo, with track listings and artwork as originally released in the UK, and Magical Mystery Tour, which became part of The Beatles’ core catalogue when the CDs were first released in 1987.

In addition, the collections Past Masters Vol. I and II are now combined as one title, for a total of 14 titles over 16 discs. This will mark the first time that the first four Beatles albums will be available in stereo in their entirety on compact disc. These 14 albums, along with a DVD collection of the documentaries, will also be available for purchase together in a stereo boxed set.

Within each CD’s new packaging, booklets include detailed historical notes along with informative recording notes. With the exception of the Past Masters set, newly produced mini-documentaries on the making of each album, directed by Bob Smeaton, are included as QuickTime files on each album.

The documentaries contain archival footage, rare photographs and never-before-heard studio chat from The Beatles, offering a unique and very personal insight into the studio atmosphere.

A second boxed set has been created with the collector in mind. The Beatles in Mono gathers together, in one place, all of the Beatles recordings that were mixed for a mono release. It will contain 10 of the albums with their original mono mixes, plus two further discs of mono masters (covering similar ground to the stereo tracks on Past Masters).

As an added bonus, the mono Help! and Rubber Soul discs also include the original 1965 stereo mixes, which have not been previously released on CD. These albums will be packaged in mini-vinyl CD replicas of the original sleeves with all original inserts and label designs retained.
