Although his appearance on Client's 2004 single "Pornography" was technically Carl Barat's first work as a solo artist, Barat began working on his solo career in earnest after the Libertines disbanded later that year due to Pete Doherty's increasing drug use and instability. In 2005 he signed to Vertigo Records and started writing songs, often escaping to the English countryside and Wales for inspiration. Barat also had a tumor removed from behind his ear, taking several weeks early in 2005 to recuperate. Along with working on his own material, Barat also pursued gigs as a DJ, spinning at art shows, festivals, and at Dirty Pretty Things, a club night he founded. Though he was signed as a solo artist, Barat reunited with former Libertines drummer Gary Powell for his backing band. He also released a collection of his favorite songs, Under the Influence, in summer 2005, with his own debut album expected by the end of the year. ~ Heather Phares, All Music Guide
