Brecht Yearbook 48 features a section on Brecht's and Heiner Mueller's engagement with modern living, a group of essays on "Brecht Post-2020," and additional new Brecht research on various topics. The Brecht Yearbook, published on behalf of the International Brecht Society, is the central scholarly forum for the study of Brecht's life and work and of topics relevant to him. Volume 48 opens with an article on the research that informed the 2022 exhibition Brecht's Paper War. The next section examines Brecht's and Heiner Mueller's engagement with modern living: from the housing question in the 1920s to the dramaturgical function of furniture to dialectical stage-auditorium configurations in the early GDR. The following section on "Brecht Post-2020" explores dramaturgical approaches to the learning play under pandemic conditions as well as the "spectrological" aspects of Drums in the Night. Additional new research includes essays on the critical edition of Brecht's notebooks, his reception in fascist Italy, the ambivalence of the heroic in his work, the prioritization of political parable over avant-garde aesthetics in Round Heads and Pointed Heads, boxing as inspiration for epic theater, Hegelian aspects of Refugee Conversations and The Measures Taken, and the working alliance of Brecht and Kurt Weill.
