Final answer:
The artistic differences of Sgt Pepper from previous albums lie in its pioneering visual and musical style, reflecting the 1960s cultural shift and integrating Pop Art into music, with innovative studio techniques and thematic cohesion.
Step-by-step explanation:
The "artistic" difference between the album Sgt Pepper and all previous albums can be understood in terms of the evolution in artistry that encompasses both the visual and musical components of the album.
From an artistic standpoint, Sgt Pepper represents a significant departure in style, presentation, and thematic content from earlier records. The album is notable for its elaborate cover design, which features a collage of famous figures, and its pioneering studio techniques, which helped to redefine the possibilities of popular music. Reflecting the cultural shift of the 1960s, it embraced the spirit of experimentation and broke away from the traditional format of the pop album by presenting a consistent theme throughout, connecting the songs with complex arrangements, and bringing elements of art, such as Pop Art and the counterculture, into the mainstream.
The album drove the concept of the studio as a creative art space, where sounds and effects that were not possible to reproduce in live performances were used to enhance the artistic expression of the music.
