Watch Coldplay Debut New Song “Amazing Day,” Perform With Ariana Grande At Global Citizen Fest

Coldplay performed at the Chris Martin-curated charity concert Global Citizen Fest today. The band played a new song in a soundcheck yesterday, and sure enough, they officially debuted it during their set. It’s an uplifting ballad called “Amazing Day,” and Martin introduced it by saying “This is about the wonderful things on earth.” It may or may not be on their upcoming album A Head Full Of Dreams. Ariana Grande also joined Coldplay onstage to perform her song “Just A Little Bit Of Your Heart” with a little help from the band, and you can watch both performances below.
