In March 2018,
Kristen Anderson-Lopez revealed in an interview that she and her husband,
Robert Lopez, would return from the film
Frozen to write songs for its sequel
Frozen 2, having been already recorded a song for the project with the help of star
Kristen Bell. Later in the
D23 Expo presentation of that same year, Disney revealed that the soundtrack would incorporate a total of seven songs. Marketing details on the complete tracklist were unveiled on September 30, 2019, which would be released on the following November 15 distributed by
Walt Disney Records. Co-director and screenwriter
Jennifer Lee said that "the songs and score of
Frozen 2 reflect both the growth of the characters and the deepening of their story", she described the songs as "emotional, personal yet powerful, intimate but also epic". Another co-director
Chris Buck emphasized the importance of the musical team, the Lopezes, and
Christophe Beck. Additionally, he noted the impact of the vibrant and emotional musics, and said it helps deepen and expand the reach of the story. The song "
Into the Unknown", sung by
Idina Menzel as Elsa with additional vocals by Norwegian recording artist
Aurora, has been called the successor of
Frozens "
Let It Go". Anderson-Lopez stated their achievements come from brainstorming on big questions — "what is the story that we all as artists, individually and collectively, need to tell? She also disclosed their production strategy of using sensitive emotional feelings and connections to the story. According to Anderson-Lopez, the theme of a journey was a very "meta-story" for them, because it was not always clear along the way how all the songs would fit together in the final version of the film. In November 2019,
Panic! at the Disco's version of "Into the Unknown" was released as a single. Later in that same month, the Korean versions of "Into the Unknown" were also released, which would be performed by
K-pop star and
Girls' Generation member
Taeyeon. Composer Christophe Beck, who previously scored the first film, returned for the sequel, his score draws elements from Lopez and Anderson-Lopez's songs. As with the first film, Beck used Norwegian elements for the sequel's score, as well as featuring the Norwegian female choir
Cantus, with Beck stating that it gives the score a "magical" setting, yet still being "rooted in real tradition". Beck said that the film's score reflects the character's growth since the original film, stating that "[s]imilar to how Elsa and Anna have grown up since the last film, the new score has also matured and introduces more sophisticated musical concepts and thematic elements". Beck also said that he wanted the sequel's score to reflect the film's "complex and intense" emotional story while commenting that he enjoyed "exploring extreme dynamic contrasts, harmonic complexity, intricate textures with vibrant colors, and hugely expressive melodic moments". ==Track listing==
