Rooted in blues and early rock and roll, the Rolling Stones started out playing covers and were at the forefront of the British Invasion in 1964, also being identified with the youthful and rebellious counterculture of the 1960s. They then found greater success with their own material as "(I Can't Get No) Satisfaction", "Get Off of My Cloud" and "Paint It Black" became No. 1 hits in the UK, North America, Australia and Europe. "Aftermath" (1966) – their first entirely original album – is considered the most important of their formative records. In 1967, they had the double-sided hit "Ruby Tuesday"/"Let's Spend the Night Together" and then experimented with psychedelic rock on "Their Satanic Majesties Request". They went back to their roots with such hits as "Jumpin' Jack Flash" (1968) and "Honky Tonk Woman" (1969), and albums such as "Beggars Banquet" (1968), featuring "Sympathy for the Devil", and "Let It Bleed" (1969), featuring "You Can't Always Get What You Want" and "Gimme Shelter". "Let It Bleed" was the first of five straight No. 1 albums in the UK. In 1969, they were first introduced on stage as 'The Greatest Rock and Roll Band in the World'.
