The Chainsmokers was formed in 2012. The lineup includes two DJs and producers, Alexander “Alex” Pall and Andrew Taggart. The latter joined the band at the end of the year.
A year after the formation, the duo recorded their first big hit "#SELFIE" and uploaded it to SoundCloud, Vine, And Instagram. Later the successful song was rereleased under Dim Mak Records.
In the first week after the official release, the song reached the 19th spot of Billboard Dance/Electronic Songs. A week later, it edged into Billboard Hot 100 and climbed to the 16th position. The single was popular worldwide. It entered over 20 world charts and topped some of them, including Finnish and Norwegian charts. The song reached top-5 of the charts in many European countries. The variety of platinum certificates the song collected is impressive. The sudden fame made it hard to book The Chainsmokers for any event. They were busy touring the world and recording new hits.
In August 2014, the duo presented a new single “Kanye”. In 2015, they recorded “Let You Go” together with Great Good Fine Ok. However, neither of the songs managed to repeat the success of "#SELFIE". But The Chainsmokers were far from being a one-song band.
