Lefèvre studied piano and organ performance as well as singing at the Centre de Musique Baroque in Versailles, where he specialized in 17th- and 18th-century music performance. He continued his education at the Conservatoire National Supérieur de Musique et de Danse in Lyon under the direction of Brian Parsons, and then became a member of the Paris Opera’s Atelier Lyrique.
His debut was the male title role in Purcell’s Dido and Aeneas under the direction of Kenneth Weith. In 2010, he made his Paris Opera as Fiorello in Rossini’s Il barbiere di Siviglia, as well as Momus in Rameau’s Platée, the latter under the baton of Marc Minkowski. He returned in 2011 to sing Curio in Handel's Giulio Cesare and in 2012 to sing Arcas and Parque in Rameau's Hippolyte et Aricie.
This summer, Lefèvre heads to Santiago, Chile where he will sing Frédérick in Delibes' Lakme. Performances run from July 5-14 and tickets are available online.
