The Beatles were an English rock band that formed in Liverpool, in 1960. With John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the greatest and most influential act of the rock era. Rooted in skiffle, beat and 1950s rock and roll, the Beatles later experimented with several genres, ranging from pop ballads to psychedelic and hard rock, often incorporating classical elements in innovative ways. In the early 1960s, their enormous popularity first emerged as "Beatlemania", but as their songwriting grew in sophistication they came to be perceived as an embodiment of the ideals shared by the era's sociocultural revolutions.
From 1960, the Beatles built their reputation playing clubs in Liverpool and Hamburg over a three-year period. Manager Brian Epstein moulded them into a professional act and producer George Martin enhanced their musical potential. They gained popularity in the United Kingdom after their first hit, "Love Me Do", in late 1962.
