I'm familiar with "Black Sunday," which I like very much, but not "Black Sabbath." After reading this and doing some online reading about the movie, I decided to see if a DVD is available ... after sorting through a dizzying array of DVD versions, some in Italian, some in English, apparently with different dialogue, different sound effects, different editing, and different music scores, I finally settled on the MGM DVR Collection, which is supposed to be the American version, and available as a Region 1 DVD (I don't have Blu=Ray or a region-free DVD player). Apparently two of the three stories are wrongly ascribed to great writers (Guy de Maupassant and I forget the other one). The one authorship that is accurate is intriguing enough: I hadn't heard of Alexi Tolstoy but find he was a cousin of the more famous Leo and also a writer. Oddly, in the amazon description, one of the characters is named "Angelique" but that name nowhere appears in the imdb listing of characters/cast.
