Fear Street Part Three: 1666 (soundtrack)

Fear Street Part Three: 1666 (Music from the Netflix Trilogy) is the film score soundtrack to the 2021 film Fear Street Part Three: 1666, the third instalment in the Fear Street trilogy, following Fear Street Part One: 1994 and Part Two: 1978. The film is jointly scored by Marco Beltrami, Anna Drubich and Marcus Trumpp.

Since the film is set in the 17th century, that did not have any musical references to construct the soundscape; the film's score was composed with a medieval touch with Drubich experimenting on the instrumentation and sounds providing an eerie and raw sound. Trumpp's contribution was only for the film's second half as that particular episode continues from Part One: 1994.

Maisie Music Publishing and Milan Records distributed the soundtrack on July 16, 2021, in conjunction with the film's release.
