The Libertines were an English rock band, formed in London in 1997 by frontmen Carl Bar?÷t (vocals/guitar) and Pete Doherty (vocals/guitar). The band, centred on the songwriting partnership of Barat and Doherty, also included John Hassall (bass) and Gary Powell (drums) for most of its recording career. The band was part of the garage rock revival and spearheaded the movement in the UK. The band gained some notoriety in the early 2000s. Although their mainstream success was initially limited, their profile soon grew, culminating in a #2 single and #1 album on the UK Charts. In December 2004, their self-titled second album was voted the second best album of the year by NME magazine. Both of their full-length LPs were produced by Mick Jones, of the British punk band The Clash. In spite of their critical success as well as decent commercial success, the band's music was often eclipsed by its internal conflicts, stemming from Doherty's addictions to crack cocaine and heroin, which eventually led to the breakup of the band. Doherty has since stated that the breakup of the band was due to relationship difficulties between Bar?÷t and himself that were not related to his drug addictions. The members of The Libertines went on to form new bands with varying degrees of commercial and critical success.
