This double issue of Performance Research is the result of a two-year collaboration with the International Research Center <<Interweaving Performance Cultures>> at the Freie Universität, Berlin. The Center was founded in 2008 with the aim of opening up a completely new field of research: processes of interweaving performance cultures. For ten years, scholars from around the world were invited to be Fellows, conducting their own research in relation to the Center’s theme. While the word ‘interweaving’ points to a variety of practices - activities of merging heterogeneous materials, encounters between living beings and objects, processes of interaction and negotiation and the fraught undertaking of engaging with each other, entailing the risk of resistance - it also points to togetherness, tension, retreat and potential transformation. From its inception, artists were invited to take up residency at the Center, to give guest presentations, to explore radical reinterpretations of interweaving and to pursue their artistic practice within the theme. Since its concluding conference in July 2018, the Center has focused on producing a multi-volume series of scholarly publications on specific aspects of the interweaving of performance cultures. This issue will weave and curate material from many of these artist-scholars and explore different formats for the presentation of their practice – interviews, conversations, manifestos, photo-essays, artist-pages and texts.
