Sandrine Mairesse is a lyric soprano with a rich, expressive timbre, renowned for her mastery of the French repertoire and her involvement in eclectic styles and in contemporary works. Active both as a Lied and opera singer, Sandrine is a regular guest soloist on major European stages such as the Ópera de Oviedo (Spain), Opera Ballet Vlaanderen and La Monnaie (Belgium). Her latest engagements having been Ferdinand Hérold's Zampa in The Netherlands, Sandrine will next be seen on stage for the reprise of her role in Bernard Foccroulle's Cassandra at the Staatsoper Unter den Linden in Berlin.

Having discovered her passion for opera at a young age in the children's choir of La Monnaie, Sandrine went on to get a Master degree at the Conservatoire of Maastricht, before specialising in opera first at the Faculty of Music in Belgrade and then at the International Opera Academy in Ghent.

Over the years, Sandrine has built up a reputation as a fine musician with proven acting talent. She has also distinguished herself by winning the First Prize at Les Nouveaux Talents de l'Art Lyrique competition (Ans - 2018) and the Second Prize at the National Operette Competition (Brussels - 2019).

Combining her musical career with a commitment to climate activism, Sandrine is particularly keen on projects that aim to bring classical music to as wide and diverse an audience as possible. She has taken part in initiatives such as Muziek Jong voor Oud (concerts in care centres and retirement homes), Lost & Found (opera created and performed in railway stations), and Opera Caramba! which brings opera to primary school children. Sandrine is since 2024 also working in the pedagogic team of La Monnaie, where she can transmit her passion for opera to children of all ages.
