“Everglow” is a song by British rock band Coldplay. It is the fourth track from their seventh studio album, A Head Full of Dreams. The song features uncredited guest vocals by Gwyneth Paltrow, the ex-wife of Chris Martin. The song was served as a promotional single of the album and released on 26 November 2015. The track was also premiered during Zane Lowe’s Beats 1 radio show.
Martin came up with the idea for the title of the song from a slang word he heard from a surfer. In an interview with Zane Lowe, he explained the origin of the phrase: “I was in the ocean one day with this surfer guy, who spoke just like you’d imagine a surfer guy to speak … This guy spoke like Sean Penn’s character from Fast Times at Ridgemont High. He was like, ‘Yo dude, I was doing this thing the other day man, it gave me this total everglow!'”
