Hermann Nitsch is one of the most famous international artists of the second half of the XX century. He’s the main exponent of the Wiener Aktionismus (with Günter Brus, Otto Mühl and Rudolf Schwarzkogler) that around the 60s become the major expression of the European Body Art movement. Between 1957 and 1960 Nitsch developes the Orgies Mysteries Theater, an expression of total art (Gesamtkunstwerk) related to the psycho-analytical concept of Abreaction, an emotional motion that allows a subject to remove the effects of dramatic events. In 1974 he meets Peppe Morra and one of his actions (45.aktion) takes place in the Studio Morra and causes his expulsion from Italy.From that moment the Studio Morra becomes his main gallery and his publisher.
