Born in Lausanne to a French father and a Bolivian mother, Marc Leroy-Calatayud studied conducting in Vienna and Zurich with Mark Stringer and Johannes Schlaefli. Furthermore, he participated in masterclasses with conductors such as Jurowski and Haitink.
From 2016 to 2019, he was an assistant conductor at the Opéra National de Bordeaux (the Bordeaux National Opera). He was also an assistant at the Akademie Musiktheater heute (2018-2021). Passionate about opera, he has developed a vast operatic repertoire, from Händel and Mozart to Ravel, Weill or Rihm. His interest in dance led him to direct several iconic productions, including The Concert, Petite Mort, La Fille Mal Gardée and Cendrillon at the Opéra National de Bordeaux (the Bordeaux National Opera), as well as a double programme choreographed by Maliphant at the Opéra National de Lyon in 2019. He also conducted the Musikkollegium Winterthur Orchestra, the Orchestre Symphonique et Lyrique de Nancy, the Orchestre de l'Opéra de Limoges and the Janáčkova filharmonie Ostrava (the Janáček Philharmonic Orchestra).
Future engagements include collaborations with the Orchestre National du Capitole de Toulouse, the Real Fhilharmonía de Galicia, the Orchestre de Chambre de Lausanne (the Lausanne Chamber Orchestra) and the Orchestra della Toscana (the Orchestra of Tuscany) . He will also make his debut with the National Ballet of Japan to conduct Roland Petit's production of Coppelia.
A strong advocate of music education and outreach projects, he founded a youth symphony orchestra, Orchestre Quipasseparlà, in 2009 to find new ways to make music accessible to all. He also creates introductory opera videos on his YouTube channel to share operatic masterpieces with as many people as possible.
