While working together on Pnau, Littlemore and Steele started writing tracks for a side project, initially called Steelemore, which became the electro pop group Empire of the Sun. Littlemore was living in Sydney and Steele, then in Perth, however the pair corresponded and continued composing together. Periodically during 2007, Steele would fly to Sydney where tracks were recorded for Empire of the Sun's debut album, Walking on a Dream. Mayes assisted with recording and mixing.
