As the lead singer for the Rolling Stones, Mick Jagger is one of the most popular and influential frontmen in the history of rock & roll. Jagger fronted the Rolling Stones for over 20 years before he began a solo career in 1985. At the time of the release of his debut solo album, She's the Boss, it appeared that the Stones may have been approaching the end of their career, but it soon transpired that Jagger's solo career would run concurrently with that of the band's.
