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."
Elena da Feltre Elena da Feltre is an opera in three acts by 19th-century Italian composer Saverio Mercadante from a libretto by Salvatore Cammarano, well known as librettist of Donizetti's "Lucia di Lammermoor" and Verdi's "Il trovatore". The premiere took place at the Teatro San Carlo in Naples on 1 January 1839 as part of the Carnival Season. While not successful at the time, the opera was revived at La Scala in 1843 with twenty performances.
