Released just three years after the band's official break-up, "The Blue Album" put The Beatles' later-year tracks into one package (released simultaneously with "The Red Album") featuring key songs from the group’s albums as well as standalone singles. With music that signified the group's own development as well as the culture around them, this selection of material from albums such as Sgt. Pepper and Abbey Road contains some of their most radical studio experiments and most loved songs.
