Sgt. Pepper's Lonely Hearts Club Band is the eighth studio album by the English rock band the Beatles. Released on 1 June 1967, it was an immediate commercial and critical success, spending 27 weeks at the top of the albums chart in the United Kingdom and 15 weeks at number one in the United States. Time magazine declared it "a historic departure in the progress of music" and the New Statesman praised its elevation of pop to the level of fine art. It won four Grammy Awards in 1968, including Album of the Year, the first rock LP to receive this honour.
In August 1966, the Beatles permanently retired from touring and began a three-month holiday from recording. During a return flight to London in November, Paul McCartney had an idea for a song involving an Edwardian era military band that would eventually form the impetus of the Sgt. Pepper concept. Sessions for what was to become the Beatles' eighth studio album began on 24 November in Abbey Road Studio Two with two compositions inspired from their youth, "Strawberry Fields Forever" and "Penny Lane", but after pressure from EMI, the songs were released as a double A-side single and were not included on the album.
