Early in production, Durkin sent Parry a playlist he had been listening to while writing the film, including songs by
Tom Petty,
Blue Öyster Cult,
Rush,
George Harrison, and
Bruce Springsteen. Initially, the only specific direction Durkin gave Parry was that he wanted the score to include "big drums." At his studio, Parry began writing and recording "power rock" instrumentals that he thought would fit the feel of the film. However, after viewing a first cut of the film and realizing how heavy it was, Durkin abandoned his "big drums" idea and Parry began composing more "claustrophobic and eerie" pieces featuring
French horn,
upright bass, and orchestral drums. Parry and his wife
Laurel Sprengelmeyer wrote an original song for the film called "Live That Way Forever", although it was not included on the soundtrack album. It instead received a separate digital release on January 3, 2024. When Parry and Sprengelmeyer first played the song for Durkin, Durkin immediately loved it and rewrote portions of the film to accommodate its inclusion. In the film, the song is performed by
Stanley Simons, who plays
Mike Von Erich. The song also plays during the film credits. ==Track listing==
