As a performer, Gaudreau has worked with opera companies throughout the United States. He has sung and understudied a variety of roles including Sid in Benjamin Britten’s Albert Herring, Des Grieux in Massenet’s Le Portrait de Manon, Figaro in Rossini’s The Barber of Seville, Aeneas in Henry Purcell’s Dido and Aeneas, Billy Bigelow in Rodgers and Hammerstein’s Carousel, Yamadori in Puccini’s Madama Butterfly, Masetto and Don Giovanni in Mozart’s Don Giovanni, Alvaro in Daniel Catàn’s Florencia en el Amazonas, and Hannah Before in Laura Kaminsky and Mark Campbell’s As One. Gaudreau was a Bonfils-Stanton Studio Artist and Apprentice Artist for two seasons with Central City Opera, and Artist-in-Residence with both Pensacola Opera and Opera on the James. Gaudreau is a staff singer at Trinity Church in the City of Boston. Formerly, he sang at Calvary-St. George’s Parish in New York. 

As a guest artist, Gaudreau has sung Ligeti’s Aventures and Nouvelles Aventures, and Schumann’s Spanische Liebeslieder in two installments of the First Monday Concert Series at Jordan Hall and recorded Pavel Haas’ Four Songs on Chinese Poetry for an NEC Liederabend. In a repeat performance of Ligeti at Boston Symphony Hall, Corey was hailed by Boston Music Intelligencer as a baritone with “vitality and precision,” offering “a fascinating study of shifting sonorities and sonic possibilities.”

A versatile singer with flexibility in various styles, Gaudreau has been heard in concert and oratorio in the United States and Europe. He is a proponent of new music, jazz, and musical theatre, and the intersections of these styles. He has sung a program of the Great American Songbook at the Isabella Stewart Gardner Museum in Boston and performs prolifically as a song recitalist and concert artist. This season, he joins pianist Cameron Stowe in presenting a recital program of Barber, Britten, Ravel, and Poulenc, inspired by legendary singers.
