Hazbin Hotel (Original Soundtrack) is an extended play soundtrack album released in three parts from the first season of the adult animated television musical series Hazbin Hotel. The first part was released on January 19, 2024, the second on January 26, and the third on February 1. The music was composed and written by Andrew Underberg and Sam Haft.
After the success of the 2019 pilot episode of Hazbin Hotel, series creator Vivienne "VivziePop" Medrano began to work on season one of the series in collaboration with A24, Bento Box Entertainment, and Amazon MGM Studios.
A24, an independent entertainment company, picked up the series for production in August 2020. In December 2021, the official Hazbin Hotel Twitter account teased the first season's release. The original release date was intended to be summer 2023, but due to the 2023 Writers Guild of America strike the production of the series was stalled and the release was pushed back to January 2024.
On November 27, 2023, Amazon introduced Sam Haft from The Living Tombstone and Emmy-nominated Andrew Underberg as the composers and producers of season one. Haft previously worked with Medrano on the music for the Hazbin Hotel pilot and the soundtrack of Helluva Boss. The cast of the series was also announced in 2023, starring Erika Henningsen as Charlie Morningstar, Jeremy Jordan as Lucifer Morningstar, Stephanie Beatriz as Vaggie, and Alex Brightman as Adam.
Two singles were released before the series, with "Happy Day in Hell" being released on October 20, 2023, after its preview at New York Comic Con, and "Poison" being released on January 5, 2024. Both songs were performed in front of the live premiere audience for the first four episodes, with Medrano posting both performances to her YouTube channel on January 17, 2024.
After the release of the first four episodes on January 19, A24 Music and Amazon Prime Video released an extended play album titled Hazbin Hotel Original Soundtrack (Part 1). On January 26, the second part was released, including four total songs from "Dad Beat Dad" and "Welcome to Heaven". The final part was released on February 1, which included songs from the final two episodes of season one. A day later, the full soundtrack album was released. It included all 16 songs from the first season.
