Graduated from the Juilliard School, Devellereau was revealed to the general public by the "Voice Masters" of Monte-Carlo[2] which she won in 1997.
[3] The Opéra National de Paris welcomed her first major role - Sœur Constance - in Dialogues of the Carmelites, conducted by Seiji Ozawa, before finding her again in Parsifal, Peter Grimes, Don Carlos and Der Rosenkavalier as Sophie.
In the United States she was welcomed at the David Geffen Hall (New York), the San Francisco Opera, the Tanglewood Festival.
At the Opera, Devellereau, often described as a sparkling, mischievous and virtuoso singer, unveils the crystal of her high pitched voice mixed with play, expressiveness and vocal flexibility in libretti by Delibes, Massenet, Strauss, Britten and Honegger.
[7] She also likes Oratorio and the concert repertoire, rich in works that correspond to her vocal range: Poulenc's Stabat mater and Gloria, Mozart's Great Mass in C minor, K. 427 and Requiem, Fauré's Requiem, Pergolesis' Stabat Mater, Haydn's Creation and the Saisons and Bach's St John Passion for Oratorio.
