François Le Roux began his vocal studies with François Loup at the age of 19, later studying under Vera Rosza and Elisabeth Grümmer at the Opéra Studio, Paris; he has won international competitions in Barcelona and Rio de Janeiro. He was a member of the Lyon Opera Company from 1980-985, since when he has been a guest artist at all major European opera houses and festivals.
His wide repertoire covers the Mozart baritone roles, and a range from the Italian repertoire (Figaro, Dandini, Malatesta, Marcello) to Baroque opera - including the title roles in Monteverdi’s Orfeo and Ulisse, Campra's Tancrède, and Rameau's Castor et Pollux (Pollux) at the Aix en Provence Festival. He has also appeared in contemporary opera, notably as Henze's Der Prinz von Homburg in Munich conducted by Wolfgang Sawallisch, and has taken the title roles in world premieres of Birtwistle's Gawain at Covent Garden, Von Bose's Die Leiden des jungen Werthers at the Schwetzingen Festival and Georges Boeuf’s Verlaine Paul in Nancy and Marseille.
In addition to numerous operatic recordings for EMI, Erato, and BMG-RCA, Le Roux has released several highly acclaimed discs of the French song repertoire for EMI, REM, Hyperion and DECCA-Universal.
