However, the deal would be short-lived, and 2007 saw the band part ways with Capitol after its merger with Virgin. The band toured with the Pixies, Editors, Cut Copy, Wolf & Cub and the Horrors, and played at the Sydney and Gold Coast legs of the V Festival. The band’s first release, the Kept Low EP, was recorded and released August 2007 on Levity in Australia.
On their self-titled debut album, released in Australia independently in August 2008, they collaborated with producer Tony Cohen and mixed the album in Melbourne with Tony Espie

They unfortunately split in February of 2009 after an eventful four years.
