James Bay performed his new single, "Us," on The Voice finale Tuesday night (May 22) and surprised fans by teaming up with one of the show's coaches, Alicia Keys, for a powerful duet.

With Bay on the guitar and Keys on the piano, the duo flawlessly executed a soulful version of the song, and on Wednesday (May 23), the song was officially released on digital streaming platforms.

The original version of the song appears on Bay's second studio album Electric Light. Watch the mesmerizing performance below.

The star-studded finale also included performances from Dua Lipa, Ryan Adams, Florence + The Machine, Jennifer Hudson, Halsey, Big Sean, Julia Michaels, Jason Aldean, Kane Brown and The Voice coaches and former contestants before crowning Brynn Cartelli as the Season 14 winner. At age 15, she's the youngest person to ever win the competition show and gave Kelly Clarkson a win for her first season as a coach.
