OCW presents Mozart's Requiem

Ottawa Choral Workshops presents a compelling performance of Mozart's Requiem — one of the most dramatic, mysterious, and emotionally charged works in the choral repertoire.

Left unfinished at Mozart’s death in 1791, the Requiem has fascinated audiences for centuries. The surviving manuscript breaks off during the Lacrimosa, leaving later musicians to determine how the work might have been completed.

This performance features the acclaimed modern completion by Michael Ostrzyga, a recent scholarly reconstruction grounded in contemporary research and close study of Mozart’s compositional language. The result offers a vivid and historically informed vision of how Mozart himself may have intended the masterpiece to conclude.

Performed by the singers of Ottawa Choral Workshops alongside professional soloists and chamber orchestra, the concert combines the immediacy of live performance with fresh insight into one of classical music’s most enduring unfinished works.

Ottawa Choral Workshops brings together experienced singers from across the community to explore major choral works in focused project intensives led by conductor, pianist, and educator Roland Graham.

Each project forms a new ensemble drawn from a wider collective of singers, creating a dynamic artistic environment built around curiosity, collaboration, musical growth, and ambitious performance standards.

JUNO Award–winning soprano Kathleen Radke has performed throughout Canada, Europe, and China with ensembles including the National Arts Centre Orchestra and Montreal Symphony Orchestra. Praised for her radiant tone and expressive artistry, she appears regularly in opera, orchestral, chamber, and sacred repertoire.

Ottawa Valley mezzo-soprano Danielle Vaillancourt is recognized for her rich, velvety voice and commanding stage presence. A JUNO Award–winning recording artist with the Ottawa Bach Choir, she performs frequently with the Montreal Symphony Orchestra, Opéra de Montréal, and Les Grands Ballets Canadiens.

Canadian tenor Corey Arnold, graduate of the Oberlin Conservatory and laureate of Jeunes Ambassadeurs Lyriques, has appeared in more than thirty opera productions across Canada, the United States, and Europe. Recent leading roles include performances in Tosca, Die Fledermaus, and Cavalleria Rusticana.

Bass-baritone Joseph Song Chi trained at the University of Toronto Opera School and Italy’s Maggio Musicale Fiorentino. International appearances include performances in Beijing and Hong Kong, alongside collaborations with the National Ballet of Canada and Toronto Mendelssohn Choir.

For its Spring 2026 concert season, Ottawa Choral Workshops returns to St. Andrew's Presbyterian Church, the beautiful downtown church located at Kent and Wellington Streets opposite the Supreme Court of Canada.
