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."
Aida Aida (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Antonio Ghislanzoni. Set in Egypt, it was commissioned by and first performed at Cairo's Khedivial Opera House on 24 December 1871; Giovanni Bottesini conducted after Verdi himself withdrew. Today the work holds a central place in the operatic canon, receiving performances every year around the world; at New York's Metropolitan Opera alone, "Aida" has been sung more than 1,100 times since 1886. Ghislanzoni's scheme follows a scenario often attributed to the French Egyptologist Auguste Mariette, but Verdi biographer Mary Jane Phillips-Matz argues that the source is actually Temistocle Solera.
