This is the first time Sgt. Pepper’s Lonely Hearts Club Band has been remixed and presented with additional session recordings, and it is the first Beatles album to be remixed and expanded since the 2003 release of Let It Be… Naked. To create the new stereo and 5.1 surround audio mixes for ‘ Sgt. Pepper,’ producer Giles Martin and mix engineer Sam Okell worked with an expert team of engineers and audio restoration specialists at Abbey Road Studios in London. All of the Anniversary Edition releases include Martin’s new stereo mix of the album, which was sourced directly from the original four-track session tapes and guided by the original, Beatles-preferred mono mix produced by his father, George Martin. This expanded 2CD package features the new stereo album mix on the first CD and adds a second CD of 18 tracks, including previously unreleased complete takes of the album’s 13 songs, newly mixed in stereo and sequenced in the same order as the album. The second CD also includes a new stereo mix and a previously unreleased instrumental take of “Penny Lane” and the 2015 stereo mix and two previously unreleased complete takes of “Strawberry Fields Forever.”  The Deluxe 2CD digipak is slipcased with a 50-page booklet abridged from the box set’s book.
