The Beatles are probablythe world's most astonishing rock-'n'-roll band whose members were John Lennon, Paul McCartney, George Harrison, and Ringo Starr. They are one of the most commercially successful and critically acclaimed bands in the history of popular music.
The Beatles led the mid-1960s musical "British Invasion" into the United States. Although their initial musical style was rooted in 1950s rock and roll and homegrown skiffle, the group explored genres ranging from Tin Pan Alley to psychedelic rock. Their clothes, styles, and statements made them trend-setters, while their growing social awareness saw their influence extend into the social and cultural revolutions of the 1960s.
