Upon its release on 1 June, 1967, Sgt. Pepper's Lonely Hearts Club Band became the popular face of psychedelia. Famously, Jimi Hendrix was playing the title track live within 48 hours of the album's release. It's remained a rock touchstone, with acts ranging from ELO and Styx to Animal Collective and Neutral Milk Hotel taking inspiration from its widescreen sound and fascinating textures.
