It was the first music festival in Italy. The first opera presented was Verdi's early "Nabucco", his early operas then being rarely staged. It now takes place between late April, May and into June, typically with four operas.  - Nabucco (short for Nabucodonosor ~, English Nebuchadnezzar) is an Italian-language opera in four acts composed in 1841 by Giuseppe Verdi to an Italian libretto by Temistocle Solera. The libretto is based on biblical stories from the Book of Jeremiah and the Book of Daniel and the 1836 play by Auguste Anicet-Bourgeois and Francis Cornue, although Antonio Cortese's ballet adaptation of the play (with its necessary simplifications), given at La Scala in 1836, was a more important source for Solera than the play itself. Under its original name of "Nabucodonosor", the opera was first performed at La Scala in Milan on 9 March 1842.
