In 2022 they will give world premieres of works by Charlotte Bray and Mark Simpson. The Quartet’s 2019-2020 Wigmore Hall cycle of Brahms and Schumann featured collaborations with Stephen Hough, Cédric Tiberghien, Michael Collins, Nils Mönkemeyer, Isabel Charisius, and Ursula Smith. In 2018, they recorded the complete Haydn Opus 76 quartets for the Wigmore Live label.

Formed in 2011, the Castalian String Quartet studied with Oliver Wille at the Hannover Hochschule für Musik, soon winning 1st Prize at the 2015 Lyon Chamber Music Competition and 3rd Prize at the 2016 Banff International String Quartet Competition. Their mentors include Simon-Rowland-Jones, David Waterman and Isabel Charisius. In 2016, the Quartet were selected by the Young Classical Artists Trust, and more recently were named recipients of the inaugural Merito String Quartet Award/Valentin Erben Prize and a 2018 Borletti-Buitoni Trust Fellowship.

In only a few seasons, the Quartet have made critically-acclaimed debuts at New York’s Lincoln Center, Banff International String Quartet Festival, the Vancouver Recital Series, Montreal’s Salle Bourgie, and The Philips Collection in Washington D.C. Other highlights include performances at the Hamburg Chamber Music Series, International Musikfest Goslar, Sommerliche Musiktage Hitzacker, and the Bath, Cheltenham and. North Norfolk, festivals. Their many notable collaborators have included Aleksander Madzar, Alasdair Beatson, Simon Rowland-Jones, Daniel Lebhardt and Olivier Stankiewicz.

When not on stage, Finnish first violinist Sini Simonen can be found hiking in the hills, Welsh second violinist Daniel Roberts follows his beloved Liverpool Football Club, Irish violist Ruth Gibson teaches yoga and English cellist Christopher Graves makes bows. Based in London, the quartet take immense pleasure in performing for diverse audiences everywhere, from great concert halls to maximum security prisons and even a rainforest.

Our name is derived from the Castalian Spring in the ancient city of Delphi. According to Greek mythology, the nymph Castalia transformed herself into a fountain to evade Apollo’s pursuit, thus creating a source of poetic inspiration for all who drink from her waters. Herman Hesse chose Castalia as the name of his futuristic European utopia in The Glass Bead Game. The novel’s protagonist, a Castalian by the name of Knecht, is mentored in this land of intellectual thought and education by the venerable Music Master. | Back to Top
