'An Evening of Erotic Diablerie' takes place on an island in the Viennese Danube on the winter solstice, celebrating the longest hours of darkness when the Sun is reborn. Based on Austria’s rich history of pagan folklore, this project weaves a narrative of sexuality, theatricality and celebration into a building (comprising of a nightclub, theatre and ritual pavilion) which bleeds in its symbolic change of gender. The project draws on the tale of Krampus; the demon that wards off Austria’s evil winter spirits. It interrogates and reconstructs this myth into a fairytale about Kralle, who is Krampus reborn as a succubus. The building sits on, is constructed from and inhabited by the Danube. The river's sediment and algae are used to construct Kralle as a breathing building with a circulatory system of algae, whilst its flow is manipulated in order to activate her change of gender. In order to perform the folktale, liquid algae's colour is manipulated and its movement controlled. At the end of the ceremony, the algae discharges back into the Danube’s side channel, guiding visitors out of Kralle's body and creating a polychromatic spectacle at the twilight before dawn.
