Isabelle Druet (born 19 September 1979) is a French operatic coloratura mezzo-soprano who has performed internationally. She began her career as an actress and co-founded a theatre company, La Carotte. She has performed in concert and recorded with the ensemble Le Poème Harmonique. On stage, she has performed at opera houses in Paris, Nancy, Lyon and Düsseldorf, among others. 　　Born in Niort (Deux-Sèvres), Druet started as an actress, taking theatre courses in high school in Salins-les-Baths. She then pursued a Diplôme d'études universitaires scientifiques et techniques (DEUST) (Diploma of scientific and technical university studies) degree in Besançon, studying at the University of Franche-Comté. Though she sang in the university choir, her musical preferences were for reggae and Indian music. In 2000, she co-founded a theatre company based in Besançon, La Carotte, where theatre, mime, music, dance and storytelling performances were mixed. Torn between theatre and music, she finally moved to Paris and studied music for two years in the 7th arrondissement before entering the National Conservatoire. 　　Studying voice at the Conservatoire de Paris, Druet graduated summa cum laude in 2007. She obtained a master's degree, writing a thesis, La construction du personnage à l'opéra, and attending masterclasses with René Jacobs and Agnès Mellon, among others. In June 2007 she won a first prize in singing with unanimous praise from the jury at the Conservatoire in Isabelle Guillaud's class. That same year, she was elected in the category "Révélation classique lyrique" of the Adami. Simultaneously with her final two years at the Conservatoire, Druet performed in the Opéra-Comique, Théâtre des Champs-Élysées, Théâtre du Châtelet, as well as at regional festivals.Among her roles were Zaïde in Europa Galante by André Campra under the direction of William Christie,which toured in 2005;[8] playing the sorceress in Dido and Aeneas, singing roles in The Clemency of Titus, and playing in the Conservatoire's productions of Eugène Onegin as Mme Larina and in Handel's Alcina as Ruggiero, among many other performances. 　　In 2008, she was awarded second place in the Queen Elisabeth Competition in Brussels, Belgium and sang at Carnegie Hall in New York City with the baroque ensemble, Les Arts Florissants under the direction of William Christie. The following year, she co-created with Marc Mauillon a presentation for the Emergence Festival. Premiering together, they performed La Valse perdue (The Lost Waltz) by Jacques Offenbach at the Musical Theater of Besançon. The duo continued to perform together, singing at the concert of the Revelations of Victories in 2010, when each of them were awarded the distinction of "laureate" in the Victoires de la musique classique. After touring throughout Europe, performing both operatic roles and singing baroque lyric concert music, Druet made her US orchestral debut performing with the Detroit Symphony Orchestra in 2015. Combining music from two different composers, Argentine Alberto Ginastera and French Maurice Ravel, the concert under the direction of Leonard Slatkin was praised for the thoughtful presentation. Druet was praised for her passionate performance in Ravel's Two Hebraic Melodies, based upon an Aramaic version of the Kaddish.Particularly noted was her performance in Ravel's Sheharazade, for her "intelligent phrasing that was seemingly attuned to every nuance embedded in the text".
