While obtaining a degree in sociology, Anaïs Bertrand studied singing at the Maîtrise Notre-Dame de Paris and then at the Conservatoire National Supérieur de Musique et Danse de Paris and with Regina Werner at the Hochschule in Leipzig. She is nourished by all forms of expression offered by vocal repertoire – from Gregorian chant to contemporary music, from polyphony to opera. In 2018, she won the 1st prize at the Froville baroque singing competition.
On stage, she has sung the role of Juno (Actéon by Marc-Antoine Charpentier) at the Royal Opera of the Château de Versailles with the Marguerite-Louise Ensemble, the role of Mélisande (Pelléas et Mélisande by Claude Debussy) with La Petite Maison as well as that of Dido (Dido and Aeneas by Henry Purcell) at the Ranelagh theatre with the Maurice et les Autres company amongst others. She has recorded with numerous Baroque ensembles, including Les Arts Florissants, Clément Janequin ensemble, Près de votre oreille, and the Marguerite-Louise ensemble, and is also sought after as a recording artist for contemporary repertoire. She also sings with numerous ensembles as a soloist including Le Poème Harmonique and ensemble Aedes (Mathieu Romano), which specializes in 20th Century acapella vocal repertoire.
