Anthony Michaels-Moore is an English operatic baritone and the first British winner of the Luciano Pavarotti International Voice Competition. Michaels-Moore has since performed in many of the world's major opera houses across Europe, the Americas, and Asia. He has distinguished himself as a specialist in Verdi and Puccini roles, most renowned for his portrayals of Falstaff, Nabucco, Rigoletto, Simon Boccanegra, Iago in Otello, Germont in La traviata, Sharpless in Madama Butterfly, and Scarpia in Tosca. In addition to the standard repertoire, he has sung and recorded the baritone roles of some of the less-known 19th Century Italian operas, as well as the popular English art song cycles by Stanford and Vaughan Williams.

Simon Boccanegra is an opera with a prologue and three acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on the play Simón Bocanegra (1843) by Antonio García Gutiérrez, whose play El trovador had been the basis for Verdi's 1853 opera, Il trovatore.
