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."
Engaged (play) Engaged is a three-act farcical comic play by W. S. Gilbert. It premiered at the Haymarket Theatre on 3 October 1877, the same year as "The Sorcerer", one of Gilbert's comic operas written with Arthur Sullivan, which was soon followed by the collaborators' great success in "H.M.S. Pinafore". "Engaged" was well received on the London stage and then in New York City, where the first production of the play opened in February 1879. The work then enjoyed many revivals on both sides of the Atlantic and continues to be produced today.
