Swiss soprano Chelsea has established herself as an artist of striking versatility, equally at home in Mozart, bel canto, baroque and the lighter Wagnerian repertoire. She made her debut at the Royal Opera House, Covent Garden as Pamina in Die Zauberflöte — a role she has also sung at Oper Köln and the Gran Teatre del Liceu in Barcelona — and her stage work has taken her to the Bayerische Staatsoper in Munich, Opernhaus Zürich, Komische Oper Berlin, Dutch National Opera and the Festspielhaus Baden-Baden.
Her repertoire reveals an unusually wide reach for a lyric soprano: the Mozart heroines Pamina and Zerlina alongside the bel canto roles of Lucia in Lucia di Lammermoor and Marie in La fille du régiment, Sophie in Massenet’s Werther, and Wagnerian assignments such as Gerhilde in Die Walküre. She is equally drawn to the baroque, having sung the title role in Handel’s Clori, Tirsi e Fileno and Serpina in Pergolesi’s La serva padrona.
On the concert platform she has appeared at the Elbphilharmonie Hamburg, the Concertgebouw Amsterdam, the Wiener Konzerthaus and the Philharmonie Luxembourg, where she shared a gala stage with Joyce DiDonato. Her concert repertoire ranges from Bach’s St John Passion and Brahms’s Ein deutsches Requiem to Mozart’s Requiem and Handel’s Messiah. She has collaborated with conductors including Kent Nagano, Maxim Emelyanychev, Alan Gilbert, Gustavo Gimeno, Andrea Marcon and Riccardo Minasi, and with period ensembles such as Il Pomo d’Oro and La Cetra.
Chelsea has enjoyed considerable success in international competition. She is a prizewinner of the 78th Concours de Genève (2024), where, alongside first prize, she was awarded nine special prizes, among them an engagement at the Grand Théâtre de Genève. At the SWR Junge Opernstars (2025) she took first prize for Female Voice together with the Emmerich Smola Orchestra Prize of the Deutsche Radio Philharmonie. Her further distinctions include first prize at the International Haydn Competition in Rohrau (2024), second prize at the Otto Edelmann Competition (2024), and second prizes at both the International Mozart Competition in Salzburg (2023) and the International Cesti Competition in Innsbruck (2022).
