COMPOSERS & MUSICIANS. The best-selling band in history, with sales of over a billion, The Beatles have had more number-one albums and sold more singles in the UK than any other act, and achieved more sales in the USA than any other artist. They became one of the most critically acclaimed acts in popular music. Formed in Liverpool in 1960, The Beatles had their roots in skiffle and 1950s rock 'n' roll, but as their career progressed they dabbled in many musical forms, including pop ballads and psychedelic rock. This book takes a look at Britain's most famous pop group, from their early days in the 1960s to the most recent activities of the surviving members, with the aid of 350 photographs.
