On the track, Gabriel delivers harmonies alongside lead vocals by Arcade Fire's Regine Chassagne.
In recent interview with the Montreal Gazette, Arcade Fire frontman Win Butler said about the collaboration, "[Gabriel] came to the studio and we had a day to work on it. He does this thing where he double-tracks his voice, high and low. As soon as he put the high vocal down, I was like, 'Oh s***, that's Peter Gabriel.'"
You can check out "Unconditional II (Race and Religion)" now at Arcade Fire's official.
The track and the album also are available via various digital and physical formats.
Gabriel previously recorded an Arcade Fire song, the Neon Bible track "My Body Is a Cage", for his 2010 covers album Scratch My Back.
