Based on the PhD research of Migros Museum für Gegenwartskunst's curator Raphael Gygax this title investigates an artistic phenomenon that started in the 1990s in the field of the performing arts, and is characterized by artists using 'other bodies' in their practices and making their 'vitality' a central part of their artworks.One of the main strategies of this approach is using the specific social roles of these other bodies, thus making the societal dimension a core element of the work--these other bodies are also described as 'extras'.This volume contextualizes the appearance of these other bodies in the broader context of the 1990s, especially in relation to Relational Aesthetics and its theoretical devices. The publication also analyses the transition from the use of a 'bio-political' body to a 'psycho-political' body, as seen over the last 30 years.Through successive case studies the author develops a typology of the 'extra body' and explores its different contexts and references. This art historical research is also linked to an investigation of the relationship between the performing body and its assimilation into the art market and the global art system.The exhibition sections, shed light on this phenomenon and its historical predecessors from the 1960s to the present day, are represented in the book by short texts and an extensive image section.Published with Migros Museum für Gegenwartskunst (Zurich, Switzerland) on occasion of the exhibition of the same title, 18 Nov 2017 - 4 Feb 2018.Part of the JRP Ringier Migros Museum series.GERMAN TEXT ONLY
