OONY, founded by conductor Eve Queler in 1971, is beloved among aficionados for its performances of opera in concert. The group puts a particular emphasis on operatic rarities, and has introduced a number of now-prominent singers, including sopranos Harolyn Blackwell and mezzo-soprano Jennifer Larmore, to New York audiences. Its 2004-05 season will end on June 6 with Weber's Der Freisch‹tz.
Giordani's previous roles with the OONY include Gennaro in Donizetti's Lucrezia Borgia, Raoul in Meyerbeer's Les Huguenots, Maurizio in Cila's Adriana Lecouvreur, and Enzo in Ponchielli's La Gioconda.
This season, Giordani appeared at the Royal Opera, Opernhaus Zurich, Deutsche Oper Berlin, Turin Opera, Metropolitan Opera, and Washington National Opera, and made his role debut as Manrico in Il trovatore at the Houston Grand Opera. This summer, he sing the title role of Andrea Ch_nier for the first time at the Macerata Summer Festival in Italy.
