This 1971 movie is definitely worth seeing, at least for a melancholically superb Jacqueline Bisset (at the same time, the other main character, Alan Alda, offers a lousy and histrionic performance). Even if it may seem obsolete, the movie still gives one chills down the spine at some moments, and the end is maybe a recognition of the fact that Evil is always more tempting than the Good. All in all, the old Faustian theme is well depicted in this movie, with some interesting arabesques (but why do the Satan worshipers speak a terrible French in their rituals - that I do not know, a superb score (naturally, since it is about the world of pianists and music) and some subtle meditations about the condition of the artist today and always. 7/10
