Coldplay has debuted another song off upcoming album "A Head Full of Dreams." Chris Martin shared "Everglow," which features guest vocals from Martin's ex-wife Gwyneth Paltrow, on Zane Lowe's Beats 1 radio show.
Martin explained to Lowe that the song's title is a word he learned from a surfer.
"I was in the ocean one day with this surfer guy, who spoke just like you'd imagine a surfer guy to speak," Martin said. "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!' I was like, 'What an amazing word.'"
Martin added, "Then the song came completely out. To me, it's about -- whether it's a loved one or a situation or a friend or a relationship that's finished or someone's passed away -- I was really thinking about, after you've been through the sadness of something, you also get this everglow. That's what it's about."
Coldplay's frontman told Rolling Stone that the song is "about a relationship's enduring spark." Regarding Paltrow's vocal contributions to the track, Martin said, "We just did it in the studio one day. It was just a friendly kind of thing."
"A Head Full of Dreams" will also feature guest vocals from Beyonce, Blue Ivy Carter, Tove Lo, Martin and Paltrow's children and Noel Gallagher, plus a sample of President Obama's rendition of "Amazing Grace." Lead single "Adventure of a Lifetime" has Coldplay fans abuzz over the album, rumored to be the band's last, which will drop Dec. 4.
