This is what we found on Wikipedia regarding the Pnau:

Pnau (stylised in all caps) are an Australian dance music trio originating from Sydney. The trio, a duo before 2016, consists of the musicians Nick Littlemore (vocals, production), Peter Mayes (guitar, production) 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 2011 album Soft Universe and an album of Pnau recreations of Elton John's hits called Good Morning to the Night, released in 2012.

Apart from being a member of Pnau, Nick Littlemore also appears as one half of the project Empire of the Sun. In November 2016, the new line-up released "Chameleon", the first single from their album Changa.
