Phoenix began recording the album during the
COVID-19 pandemic in 2020 at the
Musée des Arts décoratifs studio, which is located within the
Louvre Palace in
Paris. Laurent Brancowitz said the band "felt it would be a fantastic adventure to create something out of nothing" in an empty museum. Christian Mazzalai said that despite his initial concerns of making something while being surrounded by "too much beauty", the band "couldn't stop producing music" and that they wrote "almost all" of
Alpha Zulu within the first 10 days. The album was inspired by Philippe Zdar of the band
Cassius, who died in 2019. The song "Identical" was first released in 2020 on the soundtrack for
Sofia Coppola's film
On the Rocks. Following the song's release, frontman
Thomas Mars stated that it "goes in a different sonic direction from the LP", which feels "all over the place" and like the "same sort of weird Frankenstein of an album" that the band's debut
United is. The version of "Identical" released in 2020 has a duration of 3:13, while the listed length of the
Alpha Zulu version is 5:02. ==Artwork and title==
