Aria from La Wally

La Wally is an opera in four acts by composer Alfredo Catalani, to a libretto by Luigi Illica, first performed at La Scala, Milan, on 20 January 1892.

The opera is best known for its aria "Ebben? Ne andrò lontana" ("Well, then? I'll go far away," act 1, sung when Wally decides to leave her home forever). American soprano Wilhelmenia Fernandez sang this aria in Jean-Jacques Beineix's 1981 movie Diva – a performance at the heart of the thriller.
