Pepperland (song)
"Pepperland" is an instrumental orchestral piece conducted and composed by The Beatles' producer George Martin for the Yellow Submarine film and was the introduction to the orchestral Side 2 of the film's soundtrack album by The Beatles, released in 1969. The song was recorded by a 41-piece orchestra at Abbey Road studios on 22–23 October 1968. The piece, as with the others in the film, is tailored to the vibrant visuals of the film, so contain novelty sounds, effects, and musical experimentation that are better understood when paired with these visuals for some, however these pieces of music can also be admired for their beauty on their own.
