Верді Oberto

Oberto, Conte di San Bonifacio is an opera in two acts by Giuseppe Verdi to an Italian libretto by Temistocle Solera, based on an existing libretto by Antonio Piazza probably called Rocester. It was Verdi's first opera, written over a period of four years and it was first performed at the Teatro alla Scala, Milan, on 17 November 1839. The La Scala production enjoyed "a fair success" and the theatre's impresario, Bartolomeo Merelli, commissioned two further operas from the young composer.
