The Beatles were a highly successful and influential English rock band formed in Liverpool in 1960. Originally consisting of John Lennon, Paul McCartney, George Harrison, and Pete Best, they went through lineup changes before settling on Ringo Starr as their drummer. Managed by Brian Epstein and produced by George Martin, the Beatles saw immense popularity in the 1960s with hit songs that helped define the rock era. Their popularity grew until they ceased touring in 1966 to focus on studio recordings, though conflicts over musical direction led to their eventual breakup in 1970.
