Varèse Sarabande will release the Howard Lovecraft and the Frozen Kingdom – Original Motion Picture Soundtrack out both digitally and on CD September 23, 2016. The album features the original music composed by George Streicher.

"Being a huge Williams/Goldsmith fan, I couldn't help but bring some of that flavor to the score," Streicher stated. "Those aspects definitely come out in some of the more action-adventure driven cues in the film, but for the most part, I tried to keep things light—it is a movie for kids, after all." When scoring the first scenes, Streicher used the opening shot as inspiration for the tonal palette. "The first scene where the camera flies into the window of the house and we meet Howard for the first time I had been writing themes and playing with other ideas before, but I wanted to use that to really set the tone," Streicher concluded. "I wanted to make sure it informed the audience that the score would be big and that there would be some scale to the movie; of course then bringing it down to a more restrained tone" especially since most of the beginning of the movie is more subtle and eerie.

Howard Lovecraft and the Frozen Kingdom will be released on DVD and Blu-ray in September.
