Teenager was an art rock, punk dance band formed in 2004 by Nick Littlemore as a side project from his electronic dance group Pnau, and Phillipa "Pip" Brown (later known as Ladyhawke) on guitar (ex-member of New Zealand band Two Lane Blacktop).

In 2006 their debut single "Pony" was issued ahead of the album, Thirteen, which was followed by a second single, "Bound and Gagged". The album had been recorded over three years in studios in Sydney, London, New York, Paris and Los Angeles. The track "Pony" is featured in the soundtrack of the video game Grand Theft Auto IV. It also features Aiden Nemeth from Wolfmother on guitar. By 2007 Brown had left to pursue her solo career as Ladyhawke, and Littlemore returned to his work with Pnau and later also formed Empire of the Sun.
