Which 2026 Lollapalooza act released the 2016 hit "Closer" with Halsey?

The Chainsmokers are the 2026 Lollapalooza act that released the 2016 hit “Closer” with Halsey.

“Closer” was released on July 29, 2016, by the American electronic duo The Chainsmokers, featuring singer Halsey. The track pairs a sparse, conversational electronic-pop production with a duet between Halsey and Chainsmokers member Andrew Taggart.

The duo consists of Andrew Taggart and Alex Pall. Although The Chainsmokers first became widely known for producing and DJing, “Closer” helped establish Taggart as a prominent lead vocalist as well as a producer. The song became one of the defining pop-radio hits of 2016 and appeared on the duo’s *Collage* EP.

A common mix-up is calling it a Halsey solo song because her vocal presence is so distinctive. It is officially credited to The Chainsmokers featuring Halsey, and Halsey shares the song’s vocal spotlight with Taggart. The xx, Empire of the Sun and Major Lazer have different catalogs and are not the credited act.
