Hailed by Opera News Magazine as “superb,” and “show-stealing,” and as "a triumph" by the San Francisco Chronicle, baritone Igor Vieira made his professional debut in his native Rio de Janeiro  at age 17 singing the role of  Dancaïre in Bizet’s Carmen.

 Subsequent roles have included the title roles in Rossini's Il Barbiere di Siviglia, Mozart's Don Giovanni and Debussy's Pélleas et Mélisande as well as Junius in Britten's The Rape of Lucretia, Ford in Verdi’s Falstaff, Lescaut in Puccini’s Manon Lescaut, and most recently Tonio in Leoncavallo's I Pagliacci.

 Mr. Vieira has professionally performed 70 different operatic roles ranging from the Baroque Period to World Premiers with such companies as the San Francisco Opera, the Teatro Municipal of Rio de Janeiro (Brazil,) Opera du Villecroze (France,) Lyric Opera of Kansas City, Center City Opera, Teatro Barakaldo (Spain,) West Bay Opera, Berkeley Opera, San Francisco Lyric Opera, Fremont Opera, Rimrock Opera, Festival Opera/Walnut Creek, Oakland Opera Theater, Teatro São Pedro (Brazil,) Palácio das Artes (Brazil,) Belcantanti Opera, Pocket Opera, Opera Santa Barbara, Sacramento Opera, Opera San Luis Obispo, Abilene Opera, Fresno Grand Opera and the Opera Festivals of Belem and Manaus in Brazil.

In June of 2010, Mr. Vieira had the honor of making his San Francisco Opera debut in the role of Happy in Puccini's La Fanciulla del West, being the very first male Brazilian singer ever to perform with that company. In the Fall of 2011 Mr. Vieira returned to the San Francisco Opera stage in the role of Gubetta in Donizetti's Lucrezia Borgia with Renee Fleming in the title role, where he was favorably mentioned in virtually every published review of the production.

Mr. Vieira is a world finalist of the 1995 Luciano Pavarotti Voice Competition in Philadelphia, a recipient of the Margareth Tudor Award (Princeton) for two consecutive years and the Kaplan Foundation Award (Kansas City) for outstanding artistry. He was also awarded Second Place on the East Bay Opera League Voice Competition in 2006 and was a semi-finalist of the Competizione d'Opera in Dresden - Germany in 2008.
