"Let Me Out" is the fifth single from the band's album Humanz and was produced by Damon Albarn, Remi Kabaka and the album's executive producer The Twilite Tone. The song features guest vocals from gospel singer Mavis Staples and rapper Pusha T. The song was written by Albarn, on a train journey, when conceptualising the album, Pusha T wrote his verse upon meeting Albarn and Gorillaz co-collaborator Jamie Hewlett in London. When speaking to Zane Lowe, who premiered the song on his Apple MusicBeats 1 radio show, Pusha said "When I get over there, Damon begins to tell me to conceptualize the album as a party for the end of the world, like if Trump were to win. … I didn’t want to think about it, but that did give me a very colorful backdrop … I wrote from the perspective of this day … from the perspective of a Trump win."
