Act II: Scene 5 - O inferno!; Sento avvampar-Plácido Domingo/Giuseppe Verdi/Royal Philharmonic Orchestra/Edward Downes

Act 2， (Act 3 in the 1857 original)The Doge's apartments，[1881 revised version: There are some small adjustments in this act which include expanding Paolo's opening aria， thus giving him greater stature in the work: Me stesso ho maledetto! / "I have cursed myself"， the wording of which was originally: O doge ingrato ... ch'io rinunci Amelia e i suoi tesori? / "O ungrateful Doge! ... Must I give up Amelia and her charms".] Paolo has imprisoned Fiesco. Determined to kill Boccanegra， Paolo pours a slow-acting poison into the Doge's water， and then tries to convince Fiesco to murder Boccanegra in return for his freedom. Fiesco refuses. Paolo next suggests to Adorno that Amelia is the Doge's mistress， hoping Adorno will murder Boccanegra in a jealous rage. Adorno is furious (Aria: Sento avvampar nell'anima – "I feel a furious jealousy / Setting my soul on fire"). Amelia enters the Doge's apartments， seeming to confirm Adorno's suspicions， and he angrily accuses her of infidelity. She claims only to love him， but cannot reveal her secret – that Boccanegra is her father – because Adorno's family were killed by the Doge. Adorno hides as Boccanegra is heard approaching. Amelia confesses to Boccanegra that she is in love with his enemy Adorno. Boccanegra is angry， but tells his daughter that if the young nobleman changes his ways， he may pardon him. He asks Amelia to leave， and then takes a drink of the poisoned water， which Paolo has placed on the table. He falls asleep. Adorno emerges and is about to kill Boccanegra， when Amelia returns in time to stop him. Boccanegra wakes and reveals to Adorno that Amelia is his daughter. Adorno begs for Amelia's forgiveness (Trio: Perdon， Amelia ... Indomito – "Forgive me， Amelia ... A wild， / Jealous love was mine"). Noises of fighting are heard – Paolo has stirred up a revolution against the Doge. Adorno promises to fight for Boccanegra， who vows that Adorno shall marry Amelia if he can crush the rebels.
