A Star Is Born is the soundtrack album to the 2018 musical film of the same name, performed by its stars Lady Gaga and Bradley Cooper. It was released on October 5, 2018, by Interscope Records. Developed alongside the film's production, the soundtrack was conceived as a narrative-driven work, with songs written to reflect the characters' emotional arcs and function within the story. Cooper teamed up with Gaga's recurring collaborator DJ White Shadow and a range of musicians and songwriters, including Lukas Nelson, Jason Isbell, Mark Ronson, Diane Warren, and Andrew Wyatt. Much of the material was written during filming and evolved in tandem with the screenplay, as the production team shaped distinct musical identities for Cooper's Jackson Maine and Gaga's Ally.

Musically, the soundtrack is primarily a pop, pop rock and blues rock album, while also incorporating elements of country, folk rock, electropop, and dance-pop. Much of the music was created through a hybrid process that combined live vocals with pre-recorded instrumentation, helping recreate the atmosphere of the film. Its lyrics address love, change, personal struggle, and emotional vulnerability, while the sequencing follows the narrative progression from Jackson's rootsier material to Ally's more polished pop songs. The soundtrack was preceded by the lead single "Shallow", a major international hit, while "Always Remember Us This Way" and "I'll Never Love Again" were later released as singles in select countries.

The soundtrack received positive reviews from critics, who particularly praised Gaga's ballads, the chemistry between the two leads, and the way the music supports the film's narrative, though some felt the album was less effective outside the context of the film. It was also a major commercial success, topping charts in more than 20 countries and selling over six million copies worldwide. Among numerous accolades, "Shallow" won the Academy Award, Golden Globe Award, Critics' Choice Award, and two Grammy Awards, while the soundtrack won the Grammy Award for Best Compilation Soundtrack for Visual Media and the BAFTA Award for Best Film Music.

Background and development In March 2015, Warner Bros. announced that Bradley Cooper was in talks to make his directorial debut with A Star Is Born, the fourth iteration of the 1937 film of the same name. Music supervisors Julia Michels and Julianne Jordan had sought to work on the project since an earlier incarnation involving Clint Eastwood and Beyoncé, and eventually joined Cooper's version. American singer Lady Gaga was officially attached to the film in August 2016, with the studio green-lighting the project to begin production in early 2017. Cooper decided to cast Gaga after seeing her perform Édith Piaf's "La Vie en rose" (1947) at a charity event, which he said "blew [him] away" and led him to envision her as Ally. Gaga had performed the song for years before the film, and a rendition was later also recorded for the film and its soundtrack. In A Star Is Born, Cooper plays Jackson Maine, an established country singer who discovers and falls in love with Ally, a struggling singer-songwriter, portrayed by Gaga in her first lead feature-film role. Her rise to fame unfolds alongside his personal and professional decline, with Ally's success increasingly eclipsing Jackson’s fading career.

Cooper spent two-and-a-half years prepping for the film and determining what kind of musician his character would be. Gaga "helped inform Cooper's performance as a musician", advising him, "Work, and then you'll figure [it] out". As part of the preparations, Cooper set up a six-month "boot camp" at his Los Angeles home, where he learned guitar and piano and trained his voice to sing like a seasoned professional. He worked with vocal coach Roger Love and other musicians. Cooper said that, by the end of the process, Jackson "started developing into his own sort of creation"; if he had had another year of preparation, the character's music would have been "complete rock", but instead became "some sort of hybrid".

Writing and recording

Cooper described the soundtrack "an evolution, like the story." Gaga and Cooper were writing songs for the soundtrack during filming, with each track going through numerous iterations. Cooper added that "the music really became a character in the movie. There is no lyric that's ever in any point of the movie that doesn't have exactly to do with where one of them is or hopes to be or regrets being. That was our launching pad and then it was just about discovering what songs fit in the right places." Michels recalled hearing Gaga perform songs for the team at her kitchen table and described the early collaboration between Gaga and Cooper as "poignant, soulful and special". She and Jordan subsequently followed the songwriting process, observing how Gaga wrote and selected collaborators and how Cooper developed his own material; Michels said the songs and story continually informed one another. Changes to the film's script also influenced the music; for example, "Shallow" was initially conceived as a solo song by Ally for the end credits, when the story ended with Jackson dying by drowning—an idea that informed the song's imagery—before it was reworked into a central love song between the film's protagonists.

Jason Isbell wrote "Maybe It's Time" to help define Cooper's character, Jackson. Initially reluctant to participate, he agreed after reading the screenplay, which he described as "honest and human". He sent the song to Cooper via Dave Cobb, a Nashville-based producer he had been working with, who later played it for Gaga and Cooper during a writing session in Los Angeles, where it impressed them and helped set the tone for the soundtrack. The song became Jackson's signature song, and Cooper later called it "the staple, the sword with which a lot of the music spawned from [him]" for the rest of the album. Cooper approached Lukas Nelson after seeing him perform at Desert Trip in October 2016 and asked him to work on the film as a music consultant. Nelson said he began "writing songs for the movie, just for the heck of it, and sending them over to the producer, and they started liking them. Then Lady Gaga came by and I met her and we clicked. We became good friends, and we started writing together." Gaga, in turn, provided backing vocals on two tracks on Nelson's self-titled album released in 2017. Nelson and his band, Lukas Nelson & Promise of the Real, appear in the film as Cooper's backing band.

Gaga reunited with producer Mark Ronson and songwriter Hillary Lindsey, who had both contributed to her previous studio album Joanne (2016). According to Ronson, his previous collaboration with Gaga on Joanne helped establish the creative intimacy behind "Shallow", which she wrote in character as Ally while also drawing on her own emotions and personal experiences. Gaga worked with recurring collaborator Paul "DJ White Shadow" Blair on the soundtrack's more pop-oriented numbers performed by her character Ally, as well as producers such as Nick Monson and Mark Nilan. Monson recalled that Gaga was deeply immersed in her role while writing and recording, often discarding vocal takes if she felt they did not align with how Ally would perform them, and described the sessions as highly improvisational, requiring collaborators to quickly adapt to her ideas. Blair described the songwriting process as a "moving target", with multiple songs and iterations created for each moment in the film, and said that Ally's material was written separately "in a bubble" to preserve the character's perspective. Diane Warren—previously a collaborator on "Til It Happens to You" (2015)—contributed songwriting on "Why Did You Do That?", which she said was written as a "cool and fun" pop song, with a "bit of a retro/modern feel" outside her usual style.

The songwriting process often continued directly into recording; for example, "Always Remember Us This Way" was recorded immediately after being written, with its songwriters also providing backing vocals during the session. During Gaga's Joanne World Tour (2017–2018), parts of the soundtrack were written and recorded on a mobile studio set up on her tour bus, where she and her collaborators would continue working on songs after her shows. As the album neared completion, last-minute changes were still being made in the studio; Monson recalled that string arrangements for songs such as "I Don't Know What Love Is" were expanded shortly before recording, and that an additional arrangement for "Before I Cry" was created and recorded within hours during the same session. For the film's closing performance of "I'll Never Love Again", multiple versions of the song were prepared in different tempos and keys so that the delivery could be adjusted during filming. The scene was recorded shortly after Gaga learned of the death of her close friend Sonja Durham, which informed the emotional intensity of the live vocal.

Much of the film's music was created through a hybrid production process shaped by Gaga's insistence on avoiding lip-syncing. Vocals were recorded live on set, while instrumental tracks were typically recorded in advance and played back during filming to ensure continuity between takes. To further enhance realism, the production team captured the acoustic characteristics of each venue so the performances would match their onscreen environments. Concert scenes were often filmed in front of large groups of extras, including invited fans, who generally could not hear the backing music during takes because it was played through earpieces to prevent unreleased material from leaking; their reactions were recorded separately and incorporated into the final mix. According to engineer Benjamin Rice, the recordings were designed to sound live in the studio—raw, natural, and gritty—while each song was shaped around the story and the contrasting musical identities of Jackson and Ally. For example, Cooper envisioned "Out of Time" as a gradually building song meant to draw Ally toward the stage, mirroring the scene in which she is persuaded to join Jackson in concert. For the soundtrack album, Gaga and Rice reworked the film recordings into album mixes and incorporated dialogue excerpts to retain narrative context.

Composition

The soundtrack of A Star Is Born has been described as primarily a pop, pop rock and blues rock album. It also incorporates elements of country, rock, folk rock, electropop, and dance-pop. An article by Paper divided the songs of the album into two categories: earthy tracks reminiscent of Joanne rootsy style, and upbeat pop songs in the vein of Gaga's on-screen persona, Ally. The soundtrack conveys the film's plot through its musical progression, moving from Jackson's Americana through the pair's duets to Ally's flashier pop material, before culminating in "I'll Never Love Again". The album blends live and studio recordings with ambient noise and audience feedback, helping recreate the atmosphere of the film and its concert performances. According to Billboard Karen Bliss, its lyrics are about wanting change, its struggle, love, romance, and bonding, describing the music as largely "timeless, emotional, gritty and earnest. They sound like songs written by artists who, quite frankly, are supremely messed up but hit to the core of the listener."
