Billy Thorpe and the Aztecs were an Australian pop and rock group dating from the mid-sixties. The group enjoyed huge success in the mid-1960s, but split in 1967. They re-emerged in the early Seventies to become one of the most popular Australian hard-rock bands of the period. As is typical of many Australasian groups of the era, The Aztecs went through many incarnations. Originally formed in Sydney in 1963, the first lineup consisted of lead singer Billy Thorpe, whose powerful voice and showmanship have made him one of the most popular and respected rock performers in Australian music.
