31 Days of Halloween: The Call of Cthulhu Soundtrack
Composer Graham Plowman has written a soundtrack to the classic HP Lovecraft story, "The Call of Cthulhu". It's available for sale on Amazon, and can also be heard on YouTube (through the composer's own channel, so it should be official and legal). If they sound inspired by the soundtrack to the original series of Omen films, they should. According to the notes, that was one of Plowman's inspirations. Great stuff, and certainly good ambient music for a Call of Cthulhu game session.
