After studies at the Conservatoire (CNR) in Caen, Claire Lefilliâtre worked with Alain Buet at the National Music School in Alençon, where she was awarded a prix d’excellence. Fascinated by Baroque expression, she then trained in declamation and Baroque theatrical gesture with Eugène Green and Benjamin Lazar, and she has carried out personal work on the interpretation of seventeenth-century French and Italian music. Her thorough knowledge of the Baroque repertoire makes her much sought after by early music ensembles and she appears at many venues in France and abroad. Since 1999 she has been the principal interpreter of the productions of Le Poème Harmonique, directed by Vincent Dumestre. Her concerts and recordings with the ensemble have been unanimously acclaimed by the press, which recognizes in her work a new approach to the interpretation of Baroque music. In 2004 she took the female role in the vocal intermèdes of Molière’s Le Bourgeois Gentilhomme, and in 2006 she took the title role in Marazzoli’s opera La Vita Humana. In January 2008 she played Hermione in Lully’s Cadmus and Hermione (conducted by Vincent Dumestre, staged by Benjamin Lazar). Also in 2008, she took the part of Annius in Mozart’s La Clemenza di Tito (conducted by Jérémie Rhorer, staged by Alain Garichot). In April 2010 at the Scène Nationale in Quimper, Claire Lefilliâtre gave the first performance of Au web ce soir, libretto and staging by Benjamin Lazar, to original music by Morgan Jourdain. The same year, she gave concerts with the singer Emily Loizeau. In 2012 she will be taking part in Cavalli’s Egisto (conducted by Vincent Dumestre, staged by Benjamin Lazar) at the Opéra Comique in Paris and at the Opéra de Rouen-Haute Normandie, and in Ma Mère Musicienne, a new work by and with Benjamin Lazar, in Quimper (Scène Nationale).
