Scottish-German mezzo-soprano Catriona Morison came to the attention of a wider audience in 2017 when she won the Main Prize as well as sharing the Song Prize of the internationally renowned BBC Cardiff Singer of the World competition. At that time she was an ensemble member of the Wuppertal Opera for two seasons (2016-2018), where she added a variety of roles to her repertoire, including Nicklausse (Les contes d'Hoffmann), Charlotte (Werther), Hänsel (Hansel und Gretel), Maddalena (Rigoletto), Little Arab (Juliette) Princess Clarice (The Love for Three Oranges) and Cherubino (Le nozze di Figaro). Guest engagements in opera have taken her to the Edinburgh International Festival, Cologne Opera, Bergen National Opera and the National Theater Weimar, among others. In 2015 she made her debut at the Salzburg Festival under Franz Welser-Möst as a member of the Young Singers Project, and in the same year she sang at the Salzburg Whitsun Festival. In May 2021, she returns to Wuppertal Opera in a new production of Strauss' Ariadne auf Naxos under Patrick Hahn. She will also make her debut at the Hamburg State Opera. In the autumn of 2023, she will make a guest appearance as Meg Page in a new production of Falstaff in Bordeaux. Her recent success and debut as Der Komponist in Louisa Muller’s semi-staged production of Ariadne auf Naxos at the Edinburgh International Festival under Lothar Koenigs gained her lauded reviews.

On the concert platform, Catriona Morison made her debut at the BBC Proms in summer 2019, performing Elgar's Sea Pictures with the BBC National Orchestra of Wales under Elim Chan. She also sang the world premiere of Errollyn Wallen's This Frame is Part of the Painting, a work commissioned for her, also at the BBC Proms. In 2021/22 the artist continues to be in demand internationally: with Berlioz 'Les nuits d'été' in Granada, Edinburgh, and Glasgow, with the Verdi Requiem in Hamburg, for the first time with Mahler’s Third Symphony in Kassel and Berlin, with the Mozart Requiem in Porto, with Bach's 'Christmas Oratorio' in Vienna and Madrid, with the Beethoven 9th Symphony in Tokyo, with Mahler’s Second Symphony in Hamburg and Hong Kong, with Bach's St. John Passion in Amsterdam and Mahler's 'Kindertotenlieder' in Tenerife.

Song is of particular importance to Catriona Morison. She has been a guest at the Wigmore Hall, the Edinburgh International Festival and the Leeds Lieder Festival. In September 2021 she performed with Malcolm Martineau at the Lammermuir Festival and the Lausitz Festival, and further recitals are scheduled in Oxford and Glasgow (with Malcolm Martineau), London and Barcelona (with Julius Drake), at the Schubertiade in Vilabertran (with Ammiel Bushakevitz), and at the Heidelberger Frühling as well as in Ingolstadt (duo recitals with Katharina Konradi, accompanied by Joseph Middleton). Her first solo song CD with Malcolm Martineau was released in January 2021 on Linn Records.

Catriona Morison was a BBC New Generation Artist program artist and was awarded an Honorary Professorship from the Royal Conservatoire of Scotland (RCS) in 2017. She studied at the RCS in Glasgow, the Universität der Künste in Berlin and the Hochschule für Musik Franz Liszt Weimar.
