For the first time, the prominent German artists Joseph Beuys (1921–1986), Bazon Brock (* 1936), and Wolf Vostell (1932–1998), who collaborated in the sixties, are being presented in a single publication. In addition to parallels in the content of their work, such as their examination of the Holocaust, the three friends shared certain interests in terms of their approach. All three were involved in developing teaching practices as a form of performance art and in shifting communication, discussion, and demonstrations to the heart of their work. The radical emancipation of the individual and social reform were also common goals. Not only groundbreaking for the de­velopment of the expanded concept of art, their practices also made a fundamental contribution to the performative turn and the development of participatory concepts in twentieth century art. Exhibition: ZKM | Museum für Neue Kunst, Karlsruhe 24.5.–9.11.2014, gefördert von der Kunststiftung NRW
