The album also features other musicians performing the tracks, including Mitski, David Byrne, André 3000, Randy Newman, Moses Sumney, Surrija, and yMusic.

[3] The album was released on March 25, 2022 by A24 Music[4] to positive critical reception for the composition, setting, instrument blending and collaboration of renowned artists.

The same way that you hear two seconds of a song and you know who the artist is, they wanted to use that to mark each universe and have it feel like somebody’s changing channels on a radio when you’re moving through them.

The band's lead guitarist Rafiq Bhatia had said that the creative process of scoring for a film was very different from that of their works in studio albums, as the difference is not serving another medium, or supporting what happening in the other medium, adding "Unlike scoring a film or, or creating music for dancers, or you know, any of the other kinds of collaborations that we might embark on with artists and other media, like making a record, all there is is the sound; the sound comes first.

They had created short themes with melodic cues as "it was about finding instantly recognizable melodic ideas, and then contextualizing them instantly with either idiomatic genre, nodding instrumentation, or orchestration, or doing the exact opposite, positing them in a world of sound that feels very strange, very alien, or flirting between sound design and score, where the particular 'instruments' involved are not really recognizable instruments.

[7] They recalled the recording sessions being a "surreal and crazy thing" and claimed their score work akin to a "professional recordist playing on field".

Despite running an hour and 54 minutes, the score doesn't lose coherence [...] Son Lux's broader artistic ethos are rooted in the imperative of creation, so sprawling in its possibilities as to span an entire multiverse.

"[18] Spectrum Culture's Holly Hazelwood summarized her review stating: "Everything Everywhere All at Once is a movie of rare beauty and immense magic, and the fact that this soundtrack doesn't feel incomplete without the visual element is a testament to its quality.

"[19] Debby Das of The Harvard Crimson praised Son Lux as the "perfect choice to compose the film's jarringly primal soundtrack" and stated "Watching and listening to Everything Everywhere All at Once is the closest a viewer might get to being a kid in Willy Wonka’s candy shop.

"[20] AllMusic's Marcy Donelson concluded her review of the soundtrack writing "Son Lux's part in Everything Everywhere All at Once may or may not have raised the game in scoring as much as the joyously absurdist film has defied limitations in storytelling, but at the very least, it's a brilliant pairing.
