Are "Lady Macbeth of the Mtsensk District" and "Iphigénie en Tauride" both operas?
Lady Macbeth of the Mtsensk District (opera) Lady Macbeth of the Mtsensk District (Russian: "Леди Макбет Мценского уезда" , or "Ledi Makbet Mtsenskogo uyezda") is an opera in four acts and nine scenes by Dmitri Shostakovich, his Opus 29. The libretto, jointly written by Alexander Preys and the composer, is based on the novel of the same name by Nikolai Leskov. (The opera is incorrectly named "Lady Macbeth of Mtsensk" on several commercial CD and DVD recordings.)
Die Maccabäer Die Maccabäer ("German, The Maccabees") (sometimes spelt 'Die Makkabäer') is an opera in three acts by Anton Rubinstein to a libretto by Salomon Hermann Mosenthal. The opera is based on a play by Otto Ludwig, which is itself based loosely on the biblical story of the Maccabees. Written in 1872-74, it was first performed on 17 April 1875 at the Hofoper, Berlin. Censorship problems prevented its performance in Russia until January 1877 (in St.Petersburg).
