A production duo featuring Andrew Taggart and Alex Pall, the Chainsmokers mix indie, dance, and pop into a chart-topping sound that's spawned no less than ten multi-platinum singles. The pair released their official debut single in 2014, a number one dance hit called "#Selfie" that both celebrated and skewered 2010s narcissism. Two Top Ten pop hits, "Roses" and "Don't Let Me Down," followed in 2016, each of them certified at least five-times platinum. "Closer," featuring Halsey on vocals, began climbing to the top during the summer of 2016, remaining there for 12 weeks and eventually earning 12-times platinum status. In 2017, Taggart and Pall switched up their aggressive EDM approach to include more pop and indie rock touches, but remained a platinum act with singles including 2017's "Something Just like This," featuring Coldplay. Starting in 2018, they released a single each month, later collected on Sick Boy (2018) and World War Joy (2019).
