シモン・ボッカネグラ
Although Álvarez was scheduled to sing Don Carlo di Vargas and "Simon Boccanegra" at the Vienna State Opera, Ford at the Teatro dell'Opera di Roma, Ezio in "Attila" at the Metropolitan Opera, Boccanegra at both La Scala and Madrid's Teatro Real, and the title role in Ambroise Thomas's "Hamlet" at the Washington National Opera in 2010, he withdrew from several of those engagements (including "Attila", "Hamlet", and "Simon Boccanegra" in Madrid). Álvarez sang Iago in "Otello" for the Royal Opera in December 2019.
