Double 180 gram vinyl LP pressing in gatefold jacket featuring the new stereo album mix on the first LP and adds a second LP with previously unreleased alternate takes for each of the album's 13 songs, newly mixed in stereo and sequenced in the same order as the album. 2017 release, the 50th Anniversary remixed and remastered edition of one of rock music's most influential albums. The album is newly mixed by Giles Martin and engineer Sam Okell in stereo, sourced directly from the four-track masters at Abbey Road Studios in London, and guided by the original, Beatles-preferred mono mix produced by his father, George Martin. It was 50 years ago when The Beatles' John Lennon, Paul McCartney, George Harrison, and Ringo Starr astonished and delighted the world, ushering in the Summer of Love with Sgt. Pepper's Lonely Hearts Club Band, a groundbreaking masterwork that became popular music's most universally acclaimed album.
