As a record producer, he has worked with Elton John, Lover Lover, Groove Armada and Mika. From late 2009, Littlemore had worked with the Cirque Du Soleil as a composer and musical director for the touring arena show Zarkana, which debuted on 29 June 2011.

Pnau is an Australian dance music trio originating from Sydney. The trio, a duo before 2016, consists of the musicians Nick Littlemore, Peter Mayes and Sam Littlemore (production), with the latter joining in 2016. Pnau first gained recognition through their 1999 debut album Sambanova, which later won an ARIA Music Awards for Best Dance Release. Their third album, Pnau (2007), brought them further critical acclaim and success. Pnau is also recognised for a heavily publicised apprenticeship under the musician Elton John, who signed the duo after listening to the Pnau album. Several of Pnau's later projects have had John's involvement, such as the album Soft Universe and an album of Pnau recreations of Elton John's hits called Good Morning to the Night.
