Andrea and Julia are presenting a new project at the invitation of the Reina Sofia Museum in Madrid and Artea. Light Dark Light Heavy Archive consists of two interrelated parts: a dream mapping performance Walk on Water and a performative talk: What is stored in an archive? Is it an infinite library of information stored in books, objects or artworks? Or is it codified experiences, knowledge, insights, sensations and their embeddement in the context that originated them. The knowledge stored in the archive can only be transferred once it is embodied and situated in the here and now. Can we look at artworks not as something to be archived but as archives of knowledge in themselves that need to be unpacked in order to be kept alive. Light Dark Light Heavy Archive is a performative reflection on archiving attention, weather and dreams.
