In an imaginary American city, God consigns its licentious citizens to hell but they truculently reply that they are already there. Mahagonny ‘the city of nets’ is founded in the desert by three criminals on the run from the police. It is to be a city devoted to pleasure. The only god is money. So Jimmy Mahoney, the hedonistic lumberjack, is condemned to death for being unable to pay the bill for the whisky he has consumed. A testament to the fertile but fraught collaboration between composer Kurt Weill and man of theatre Bertolt Brecht, Rise and Fall of the City of Mahagonny is one of the great operas of the 20th century. Brecht might have resented the dominance of the music over the words but together they created a work with rich melody and unstoppable dramatic momentum.

La cambiale di matrimonio (The Bill of Marriage or The Marriage Contract) is a one-act operatic farsa comica by Gioachino Rossini to a libretto by Gaetano Rossi. The libretto was based on the play by Camillo Federici (1791) and a previous libretto by Giuseppe Checcherini for Carlo Coccia's 1807 opera, Il matrimonio per lettera di cambio. The opera debuted on 3 November 1810 at the Teatro San Moisè in Venice Composed in a few days when he was 18 years old, La cambiale di matrimonio was Rossini's first professional opera. The overture, written when he was a student at the Liceo Musicale in Bologna, is an important part of the modern concert repertoire. As was to become typical of his later career, the duet "Dunque io son" was later reused, to greater effect, in act 1 of The Barber of Seville
