The release of Sgt. Pepper’s Lonely Hearts Club Band is considered not only a milestone in terms of The Beatles discography, but also in 20th century pop music. With this concept album, in which the band experimented with very different rhythms and subjects, and full of references to the 1960s context, the Fab Four left a musical legacy that is still with us today. Three fans and admirers of The Beatles talk to Rulo about the album that revolutionised music history. With the musician and writer Joselo, the novelist and screenwriter Hanif Kureishi, and the academic and writer Carmen Pardo.
