The Beatles were a highly influential English rock band formed in the 1960s consisting of John Lennon, Paul McCartney, George Harrison, and Ringo Starr. They gained popularity in the UK and US with hits like "Love Me Do" and TV appearances. Their albums became increasingly experimental throughout the 1960s, incorporating many genres of music. Internal disputes led to the band breaking up in 1970 after releasing acclaimed albums like Sgt. Pepper's Lonely Hearts Club Band and Abbey Road. Each member then pursued successful solo careers.
