Coloratura soprano Cyndia Sieden has made regular appearances at the world’s great opera houses and concert stages, singing roles from 17th and 18th-century works to 20th and 21st-century repertoire. She made her debut at the Metropolitan Opera in Berg’s Lulu and received critical acclaim as Ariel in the world premiere of Thomas Adès’ The Tempest at the Royal Opera House Covent Garden and in the North American premiere at the Santa Fe Opera. She created the role of Ratastok in Sunlief Rasmussen’s Second Symphony with the Helsinki Philharmonic Orchestra, sang Esa-Pekka Salonen’s Wing on Wing with the Los Angeles Philharmonic in LA and on tour in Europe and starred in the North American premiere of Morton Feldman’s monodrama Neither (New York City Opera). She also starred in the premiere production of Wolfgang Rihm’s Dionysus (Netherlands Opera/ Holland Festival) and was the Cheshire Cat in the second production of Unsuk Chin’s Alice and Wonderland in Geneva.

She has garnered acclaim as Queen of the Night in Mozart’s Die Zauberflöte and Blondchen in Die Entführung aus dem Serail (both recorded with John Eliot Gardiner and the English Baroque Soloists for Deutsche Grammophon), having sung the Queen of the Night at Munich’s Bayerische Stattsoper, Paris’s Opera Bastille, La Monnaie, the Metropolitan Opera and many other opera houses all over the world. Her decades-long collaboration with the Orchestra of the 18th Century culminated in an acclaimed recording of the seven concert arias Mozart wrote for Aloysia Weber. She has sung at the Salzburg Festival as Aspasia in Mozart’s Mitridate and Amor in Gluck’s Orfeo, as well as in a staged and filmed Mozart concert aria project - Ombra Felice - and in concerts as varied as Mozart’s Mass in C Minor and the epic and rarely performed Prometeo by Luigi Nono.
