The Rolling Stones are an English rock band formed in London in 1962. Active for six decades, they are one of the most popular and enduring bands of the rock era. In the early 1960s, the Rolling Stones pioneered the gritty, rhythmically driven sound that came to define hard rock. Their first stable line-up consisted of vocalist Mick Jagger, multi-instrumentalist Brian Jones, guitarist Keith Richards, bassist Bill Wyman, and drummer Charlie Watts. During their formative years, Jones was the primary leader: he assembled the band, named it, and drove their sound and image. After Andrew Loog Oldham became the group's manager in 1963, he encouraged them to write their own songs. Jagger and Richards became the primary creative force behind the band, alienating Jones, who had developed a drug addiction that interfered with his ability to contribute meaningfully. 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, becoming 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" (1965), "Get Off of My Cloud" (1965), and "Paint It Black" (1966) became international number-one hits. Aftermath (1966) – their first entirely original album – is considered by The Daily Telegraph to be the most important of their formative records. In 1967, they had the double-sided hit "Ruby Tuesday"/"Let's Spend the Night Together" and experimented with psychedelic rock on Their Satanic Majesties Request. They returned to their rhythm and blues roots with hit songs such as "Jumpin' Jack Flash" (1968) and "Honky Tonk Women" (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 consecutive number-one albums in the UK. Jones left the band shortly before his death in 1969, having been replaced by guitarist Mick Taylor. That year they were first introduced on stage as "The Greatest Rock and Roll Band in the World". Sticky Fingers (1971), which yielded "Brown Sugar" and included the first usage of their tongue and lips logo, was their first of eight consecutive number-one studio albums in the US. Exile on Main St. (1972), featuring "Tumbling Dice", and Goats Head Soup (1973), yielding the hit ballad "Angie",
