Hanns Eisler's native Vienna is the point of convergence for the approach to three complexes in his "life and works": re-emigration, film music and incidental music. At the center is the period between Eisler's return from exile in the U.S. in 1948 and the end of his compositional engagement in Vienna, which was closely connected to the withdrawal of the Soviet occupational forces from Austria in 1955. At the center of Eisler's film and incidental music are three major works which Peter Schweinhardt examines on the basis of widely unknown musical material and documents: the filming of Brecht's "Herr Puntila und sein Knecht Matti" (1955), the work on the script of the "Fidelio" screen adaptation by Walter Felsenstein (1953-56) and the incidental music to Nestroy's "Höllenangst" (1948). This lengthy score is characteristic of Eisler's post-war project of a new, folkloristic-classicistic music.
