In January 2009 she began working on what would become her debut album, alongside a myriad of names and faces such as Ellie Goulding, Starsmith, and Guy Sigsworth. However, the process was a slow one, and Vickers labored over the album for more than a year without any released material to show for it. She did, however, appear in the West End production The Rise and Fall of Little Voice, winning best newcomer at the theatre awards.
