They were considered to be symbols of rebellious youth in their mid-1960s heyday, and were portrayed as the "Anti-Beatles". During this time they scored a string of hit singles, many reaching the top of the international charts, particularly in the UK and US. They received a great deal of backlash upon the release of Their Satanic Majesties Request (1967), created as a reaction to The Beatles' Sgt. Pepper's Lonely Hearts Club Band. Into the late 1960s and early 1970s the band released Beggars Banquet (1968), Let It Bleed (1969), Sticky Fingers (1971) and Exile on Main St. (1972). This string of four albums is considered to be the band's "Golden Age", and generally regarded as their finest work. After a period of criticism during the mid-1970s, they revived their commercial fortunes and popular appeal with 1978's Some Girls, their best-selling studio album. Since this time through band friction and solo projects, they have released material less frequently, but have remained commercially popular and continue to embark on highly successful worldwide tours.
