French tenor Sébastien Guèze has built an international career of more than 500 performances and over 50 leading roles across Europe, America and Asia. A graduate of the Conservatoire National Supérieur de Musique et de Danse de Paris, he won both Second Prize and the Audience Prize at Plácido Domingo's Operalia competition.
Recent engagements include Adoniram in Gounod's La Reine de Saba at the Deutsche Oper am Rhein, hailed by critics as "the revelation of the evening", and Don José in Carmen at Opera Hong Kong.

His career has taken him to La Fenice in Venice (La Bohème, Werther), the Grand Théâtre de Genève, Leipzig, Seville and Palermo (Carmen), Amsterdam, Miami and Hong Kong (Roméo et Juliette), the Semperoper Dresden (La Traviata, Les Contes d'Hoffmann), La Monnaie in Brussels (La Traviata, La Bohème), the Deutsche Oper am Rhein (Hérodiade, La Reine de Saba), Bonn and Essen (Les Contes d'Hoffmann), Opera North (Carmen, La Rondine), Marseille and Vilnius (Manon), as well as Athens, Warsaw, São Paulo, Rome, Lausanne, Turin, Helsinki, Tokyo and numerous American companies. He covered the title role in La Damnation de Faust at the Metropolitan Opera in New York.

He has worked with conductors and stage directors including Zubin Mehta, Kent Nagano, Alain Altinoglu, Kazushi Ono, Plácido Domingo, Omer Meir Wellber, Graham Vick, Andreas Homoki, Calixto Bieito, Marco Bellocchio, Christophe Honoré and Mariusz Treliński.

Today, his repertoire centres on the great French and Italian roles: Don José, Cavaradossi, Hoffmann, Werther, Faust and Roméo. He has also sung Rodolfo, Alfredo, Des Grieux, the Duke of Mantua, Pinkerton, Maurizio, the Prince in Rusalka and Lensky.

A committed advocate of French operatic heritage, he has championed rare works such as Massenet's Hérodiade, Auber's Manon Lescaut, Grétry's Andromaque, Lalo's Le Roi d'Ys and Reyer's Salammbô. He has also created roles in new works, including Vladimir Cosma's Marius et Fanny and David Di Chiera's Cyrano in Detroit and Miami.

Beyond singing, he creates new ways to experience opera. He conceived, adapted, directed and starred in the opera-film La Bohème 2050, produced for France Télévisions with the Opéra Royal de Versailles. Set in a future shaped by climate disruption, where the heroes die of heat rather than cold, it was produced with an estimated 80% reduction in carbon emissions compared to a traditional production. In 2026, he created Tosca Immersive, an opera experienced like a film, in which the audience follows the singers through the action. He sang Cavaradossi, and the production played to sold-out houses. He also designs bespoke opera experiences for venues, companies and private clients, in France and in Asia.

He is the founder of BIOpera (www.biopera.art), an artistic and research laboratory exploring new stage forms and the future of the performing arts. He is the author of the essay BIOpera (Éditions Symétrie) and the report Decarbonising Opera, and lectures for institutions including Sciences Po Paris, the Centre National de la Musique and the Opéra national de Paris.

Passionate about teaching, he gives masterclasses for several programs, like the Association Dire et Chanter les Passions in Angers, the Paris Ouest and Paris Grand Est conservatoires, and in China. In 2025, he served on the jury of the Vocal Competition of the École Normale de Musique de Paris Alfred Cortot.

Sébastien Guèze is a Chevalier des Arts et des Lettres. On stage and beyond it, he pursues one conviction: opera is only an emotion to be shared.
