“Chemicals” is a temporary name for a track performed by Halsey and YUNGBLUD on December 6, 2018, at an event held by LAYLOW and Kensaltown Studios in London. A fan who was at the event shared a clip of the two performing the track on to their Instagram following the performance.

The song isn’t the first time the pair have worked together, collaborating on hit-single “11 Minutes,” released a few months later.

It is unknown when the track will be released, and by what artist (feature, collaborative etc.).
