Which 2026 Lollapalooza act formed in Sydney in 2007 and released Walking on a Dream?

The 2026 Lollapalooza act formed in Sydney in 2007 and released *Walking on a Dream* is Empire of the Sun.

Empire of the Sun is the Australian electronic-pop duo of Luke Steele and Nick Littlemore. Steele was already known from the alternative-rock band The Sleepy Jackson, while Littlemore was a member of the electronic group Pnau. Their partnership developed into a theatrical project built around synth-pop, elaborate costumes and a deliberately futuristic visual identity.

The duo’s debut studio album, *Walking on a Dream*, arrived in 2008. Its title track and “We Are the People” became international favorites, helping establish the group beyond Australia. The album is sometimes confused with the similarly named single, but both refer to Empire of the Sun releases: the song came first as a single, while the album contains it alongside the group’s other early material.

The answer is not The xx, Major Lazer or The Chainsmokers. Those acts also appear in the 2026 Lollapalooza lineup, but none matches the Sydney-formed duo and its signature debut album.
