About Everglow

"Everglow" is a song by British rock band Coldplay. It is the fourth track from their seventh studio album, A Head Full of Dreams. It features uncredited guest vocals by Gwyneth Paltrow, who at the time was married to Chris Martin despite their separation being announced in 2014. The track premiered during Zane Lowe's Beats 1 radio show on 26 November 2015 and was originally released as a promotional single for the album on 27 November 2015.

On 11 November 2016, however, the song was released as the fourth official single from the album through a newly recorded stripped-down version, which was inspired by Martin's unrehearsed solo performance of the song at the recent Glastonbury Festival. This recording ends with a sample of Muhammad Ali's 1977 speech in Newcastle upon Tyne. The track revolves around a heartfelt piano riff and was written in the key of C# Minor at 73 BPM and a chord progression that alternates between C#m-A-E-G#m7 and C#m-A-E-B.
