biographical info
Alfredo Catalani (1854-1893) was an Italian composer of operas including Loreley and La Wally.
La Wally was composed for a libretto by Luigi Illica, and features Catalani's most famous aria "Ebben? Ne andrò lontana."
Toscanini was a strong supporter of Catalani's music and named his daughter Wally - a reference to the composer's most successful opera.
