[fn 7] Martin Gruber developed a new foundational method for comprehensive, interdisciplinary actor training inspired by Asian and western dance, martial arts as well as many of the concepts from structural integration and functional bodywork.
In this way, his method can answer to the demands of an ever-changing theatrical landscape that is constantly searching for new modes of expression, whilst lending the skills necessary for the traditional theatre.
Since 1995 there have been premiers in the Bavarian dialect for example Wir sind Gefangene (Oskar Maria Graf), Lena Christ, Die heilige Nacht by Joern van Dyck and Bettina Mittendorfer.
Teachers at Birach include Rena Mirecka (Jerzy Grotowski's Theaterlaboratory, Polen), Paco Gonzales (Familie Flöz); Marita Günher (Roy Hart Theatre, London), Prof. Alon Talmi (Israel), William Dub Leigh (USA), Nobuyuki Watanabe (Japan).
Martin Gruber has given trainings at many international institutions e.g. Ecole Supérieure d’Art Dramatique du Théatre Nationale de Strasbourg (Frankreich), Central Academy of Drama, Beijing, and Shanghai Theatre Academy (People's Republic of China), workshops for example at Westerdals Oslo School of Arts, Communication and Technology, Oslo (Norway), National School of Drama, Delhi (India), Mozarteum, Salzburg (Austria), Hochschule für Musik und Theater München, Mime Centrum Berlin, Berlin University of the Arts, ImPulsTanz Vienna International Dance Festival (Austria)
