Arrigo Boito is remembered today for his only completed opera Mefistofele. The score for Nerone was left unfinished at the composer's death - a performing version was completed by the composers Vincenzo Tommasini and Antonio Smareglia, along with Arturo Toscanini who conducted the world premiere at Teatro alla Scala in 1924. The narrative focuses on Emperor Nero during a time of conflict between beliefs in Imperial Roman gods and Christianity, and ends with tragic dramas amidst the Great Fire of Rome. With influences that include Wagner and Sibelius, Boito's rarely performed Nerone uses a truly exciting harmonic palette delivered through a masterly handling of huge orchestral forces.
