Suspiria (1977)

Suspiria, an Italian supernatural horror film directed by Dario Argento, is a great deal of fun to watch due to its visual styling and its music by the progressive rock band Goblin.

This film is enormously influential in horror, following the story of American ballet student Suzy Banyon (Jessica Harper) who transfers to a prestigious dance academy in Germany. A note - this film's violence and infantilization of Jessica is a bit uncomfortable to watch.
