Franco Alfano Domingo in the title role. In 1921, "La Leggenda di Sakùntala" appeared, described by some as his most important stage work, and while it was successful enough to have Arturo Toscanini recommend Alfano for the completion of Puccini's posthumous Turandot, the performance materials were thought destroyed in an air raid during the Second World War. Alfano reconstructed it in 1952 as "Sakùntala", after "Abhijñānaśākuntalam" ("The Recognition of Sakuntala"), the Sanskrit play by Kālidāsa. Subsequently, the original version was recovered in 2005, with the two versions available for performance today. The second version of Sakùntala was performed in New York City
Unfinished creative work missing music had to be provided by Franco Alfano for the premiere in 1926. Recently, Luciano Berio composed an alternative ending. Alban Berg had only finished the first two acts of his opera "Lulu" at the time of his death in 1935. Due to objections from his widow it was not until 1979 that a full version was performed, with music for the final act devised by Friedrich Cerha using Berg's sketches. Other musical works which are unfinished but performable, are simply given in their incomplete state. Schubert's symphony is the most famous, but Anton Bruckner's Ninth Symphony is performed
