This volume offers a comprehensive collection of all poetic texts by Bertolt Brecht on the theme of Mahagonny. It includes the various versions of the "Songspiel" as well as the original version of the "Opera in three acts." Additionally, several drafts and new versions of individual scenes are included. All poems that Brecht included in his poetry collection Bertolt Brecht's Hauspostille are also part of the work. The volume also contains statements by Brecht and Kurt Weill about the opera and its possibilities for renewal. The history of the creation of the text and music is documented through memories of contemporaries. A particular focus is placed on the fact that Brecht completed the text for the opera before the Threepenny Opera, while Weill only composed the music for the Rise and Fall of the City of Mahagonny afterward. The turbulent history of the productions in the late 1920s and early 1930s is evidenced by numerous critiques, supplemented by a plagiarism scandal. Contemporary and new interpretations as well as analyses round out the volume.
