Returning to the lighter and more romantic style that first made them famous, The Chainsmokers deliver another summer anthem on “Side Effects”. Featuring pristine vocals from frequent collaborator Emily Warren over a beat that fuses future bass and tropical house, “Side Effects” tells a story of shedding any preconceived inhibitions to live in the moment and enjoying the fling mentioned in the song.

Originally teased by The Chainsmokers through a blank yellow post on their Instagram on July 19, 2018, the EDM/pop duo officially announced the song on July 23rd, updating their logo to a new and brighter design. After the release of the Sick Boy EP, which featured more thematically darker songs than was usual of The Chainsmokers, they announced in an Instagram comment on May 23rd about a new song that would flip the style on its head with a summer-ready beat.
