Verdi's opera Attila takes as its starting point Attila’s plans to storm Rome with his army of Huns and the Romans’ attempts to prevent him. As with Nabucco and I Lombardi, Verdi spiced up the action with a number of patriotic choruses, guaranteeing that – against the background of the Italian movement for unification – the opera was a great success. 'Michele Mariotti owes much to the fact that this evening became a celebration of voices' (Opern-Kritik). Ildebrando D´Arcangelo is 'perfect for the serious Verdi roles', Fabio Sartori has a voice of immense brilliance' (Opern-Kritik), 'Simone Piazzola was an impressive Ezio' (theoperacritic.com) and 'the real warrior of this Attila is the soprano Maria Jose' Siri … with her voice, touching each primordial sentiment in every note of the opera, she commanded ‘Attention’ from everybody' (La Repubblica).
