Norma, or A Politician's Love (Norwegian:"Norma eller En Politikers Kjærlighed") is an eight-page drama written as an opera parody by Henrik Ibsen.
 It is influenced by Vincenzo Bellini's opera "Norma", which Ibsen saw in 1851, but the characters are contemporary politicians.
 The play was first printed anonymously in the satirical magazine "Andhrimner" in 1851.
 The first book edition came in 1909, and the first performance of the play was at a student theatre in Trondheim 1994.
The "Alabama Song"—also known as "Moon of Alabama", "Moon over Alabama", and "Whisky Bar"—is an English version of a song written by Bertolt Brecht and translated from German by his close collaborator Elisabeth Hauptmann in 1925 and set to music by Kurt Weill for the 1927 play "Little Mahagonny".
 It was reused for the 1930 opera "Rise and Fall of the City of Mahagonny" and has been notably covered by The Doors and David Bowie.
Mahagonny-Songspiel, also known as The Little Mahagonny, is a "small-scale 'scenic cantata'" written by the composer Kurt Weill and the dramatist Bertolt Brecht in 1927.
 Weill was commissioned in the spring to write one of a series of very short operas for performance that summer, and he chose to use the opportunity to create a "stylistic exercise" as preparation for a larger-scale project that they had begun to develop together (the two had met for the first time in March), their experimental 'epic opera' "The Rise and Fall of the City of Mahagonny" (1930).
Norma (] ) is a "tragedia lirica" or opera in two acts by Vincenzo Bellini with libretto by Felice Romani after "Norma, ou L'infanticide" ("Norma, or The Infanticide") by Alexandre Soumet.
 It was first produced at La Scala in Milan on 26 December 1831.
"The Modern Theatre Is the Epic Theatre" is a theoretical work by the twentieth-century German theatre practitioner Bertolt Brecht.
 It was composed in 1930 as a set of notes to accompany his opera "Rise and Fall of the City of Mahagonny".
 In it, he outlines his ideas for a "refunctioning" of the theatre, his principle of the 'separation of the elements" (conceived in opposition to Wagner's principle of the "integrated work of art"), and the "shifts of accent" involved in the move from traditional "dramatic" theatre to his own "epic" theatre.
 It also contains one of the earliest formulations of "Gestus".
Inga Nielsen (2 June 1946 – 10 February 2008) was a Danish soprano who had an active international opera career from 1971 to 2006.
 A child prodigy, Nielsen performed on American radio during the 1950s, beginning at the age of six, and also released some commercial recordings of Danish folk songs and Christmas carols as a child.
 She began her opera career performing parts in the lyric soprano repertory and then became an admired singer of dramatic soprano roles, beginning in the late 1980s.
 She was a particularly renowned interpreter of the roles of Konstanze in Wolfgang Amadeus Mozart's "Die Entführung aus dem Serail" and the title role in Richard Strauss's "Salome".
 She excelled in portraying some of the more rarely heard and demanding dramatic soprano roles such as the woman in Arnold Schoenberg's "Erwartung", Ursula in "Mathis der Maler" and Jenny in "Rise and Fall of the City of Mahagonny".
Rise and Fall of the City of Mahagonny (German: Aufstieg und Fall der Stadt Mahagonny ) is a political-satirical opera composed by Kurt Weill to a German libretto by Bertolt Brecht.
