For Suspiria, Stan Douglas brings together the visual style of Dario Argento's 1977 horror movie of the same title; the properties of the now obsolete Technicolor process; the fairytales of the Brothers Grimm and a soundtrack featuring John Medeski and Scott Harding (of the celebrated Jazz ensemble Medeski, Martin and Wood). Stan Douglas's Suspiria takes as its location the Herkules Oktagon, Kassel's most famous historical landmark: a monumental octagonal structure built in the late 17th century, atop Wilhelmshöhe overlooking the city of Kassel.
