Are Lulu and Destiny both three-act operas?
Lulu (opera) Lulu (composed from 1929–1935, premièred incomplete in 1937 and complete in 1979) is an opera in three acts by Alban Berg. The German-language libretto was adapted by Berg himself from Frank Wedekind's two "Lulu" plays, "Erdgeist" ("Earth Spirit", 1895) and "Die Büchse der Pandora" ("Pandora's Box", 1904). Berg died before completing the third and final act, and in the following decades, the opera was typically performed incomplete. Since its publication in 1979, however, the Friedrich Cerha orchestration has become popular. Theodor W. Adorno wrote "The opera "Lulu" is one of those works that reveals the extent of its quality the longer and more deeply one immerses oneself in it."
L'italiana in Algeri L'Italiana in Algeri (] ; English: The Italian Girl in Algiers ) is an operatic "dramma giocoso" in two acts by Gioachino Rossini to an Italian libretto by Angelo Anelli, based on his earlier text set by Luigi Mosca. It premiered at the Teatro San Benedetto in Venice on 22 May 1813. The music is characteristic of Rossini's style, remarkable for its fusion of sustained, manic energy with elegant, pristine melodies.
