No other band has had quite the same impact as the four lads from Liverpool. Over the course of eight years and more than a dozen albums, the Beatles changed popular music and culture forever, spearheading the 1960s British Invasion and shaping rock & roll along the way. Along with their amazing musical output and unprecedented worldwide celebrity, John, Paul, George, and Ringo were responsible for many pop music revolutions, major and minor--writing their own material, pushing the limits of the studio, making films of their music, printing song lyrics on albums--that today are taken for granted. Although the Beatles disbanded in 1970, their artistic legacy is permanently ingrained in the entire world's musical vocabulary.
