This is a book on the best known of the Weill-Brecht collaborations which explores the extent and significance of the composer's contribution. After a detailed reconstruction of the work's genesis and continued revision over three decades, Stephen Hinton examines the spin-offs on which Weill and Brecht participated: the instrumental suite, the film, the lawsuit, the novel, and the musical and textual revisions of songs. In a survey of the stage history, Hinton pays particular attention to pioneering productions in Germany and Great Britain. Kim Kowalke provides an exhaustive account of the history of The Threepenny Opera in America, Geoffrey Abbott addresses questions concerning authentic performance practice, and David Drew analyses large-scale motivic relationships in the music. Among the earliest writings on the work reprinted here, those by Theodor W. Adorno, Ernst Bloch and Walter Benjamin appear for the first time in English translation. The book contains numerous illustrations, a discography, and music examples.
