Since then, she has sung on the world's biggest stages and at premier music festivals, collaborated with today's foremost conductors in operatic and symphonic repertoires, appeared on numerous television broadcasts throughout North America and Europe, and compiled a distinguished catalog of recordings. Her interpretations of Mozart's dramatic heroines, including Fiordiligi in *Cos\u00ec fan tutte*, Donna Anna and Donna Elvira in *Don Giovanni*, Elettra in *Idomeneo*, and Vitellia in *La Clemenza di Tito*, have been hailed as definitive, and she has become especially identifiable with the role of Floria Tosca. She performed the title role of Puccini's *Tosca* at the Metropolitan Opera in 2004 opposite Pavarotti in the legendary tenor's final operatic performance. Vaness made her professional debut as Vitellia for the San Francisco Spring Opera and has been acknowledged as the world's leading interpreter of this role. She has appeared as Vitellia at the Met Opera, Paris Opera, Royal Opera, Covent Garden, Chicago Lyric Opera and Gran Teatro del Liceo and at the Salzburg Festival and other leading theaters. Among her many celebrated television appearances, she has been featured on the *Pavarotti Plus* and *Pavarotti and Friends* telecasts from Lincoln Center, as well as the Richard Tucker Gala and *In Performance at the White House* with members of the New York City Opera.", "occurrence_notes":null, "guid":"145645-21897629@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/145645", "building_id":"1000440", "building_name":"Earl V.
