Collage In music, with the advances on recording technology, avant-garde artists started experimenting with cutting and pasting since the middle of the twentieth century. In the 1960s, George Martin created collages of recordings while producing the records of The Beatles. In 1967 pop artist Peter Blake made the collage for the cover of the Beatles seminal album "Sgt. Pepper's Lonely Hearts Club Band". In the 1970s and 1980s, the likes of Christian Marclay and the group Negativland reappropriated old audio in new ways. By the 1990s and 2000s, with the popularity of the sampler, it became apparent that "musical collages" had
Sgt. Pepper's Lonely Hearts Club Band that point." Harrison added that, having enjoyed recording "Rubber Soul" and "Revolver", he disliked how the group's approach on "Sgt. Pepper" became "an assembly process" whereby, "A lot of the time it ended up with just Paul playing the piano and Ringo keeping the tempo, and we weren't allowed to play as a band as much." After finishing "Sgt. Pepper", the Beatles took an acetate disc of the album to the American singer Cass Elliot's flat off King's Road in Chelsea, where at six in the morning they played it at full volume with speakers set in open window frames.
