Daughters of Darkness is a 1971 English-spoken Belgian horror film. Directed by Harry Kümel, this cult erotic vampire film stars Delphine Seyrig, Danielle Ouimet, John Karlen, and Andrea Rau. The story features a newlywed couple that stops at a posh French hotel on their way to England. They meet a beautiful, red-lipped woman whom the hotel owner swears had been there 40 years ago, even though she hasn't aged. She introduces herself as Countess of Bathory and folks begin to wonder.

It's score was created by multiple award-winning composer François de Roubaix, who is seen as a precursor of the French electronic music next to his jazz expertise. Years after it's original release, the music was picked up and sampled by several hip hop artists, such as Ice-T, Ab-Soul and Lil Wayne. Critics, actors, and directors call it one of the best horror movies ever made. A retrospective poll by Time Out in the early 2010s placed the film at number 90 in their top 100 horror films.

In 2021, we celebrate the movie's 50th anniversary. Filmfestival Gent will show the movie in it's entity with an orchestra playing the score. With the help of director Harry Kümel and Patricia and Benjamin de Roubaix, the Original Soundtrack of Daughters of Darkness is available on black vinyl and contains an exclusive poster and printed innersleeves.
