The Castalian String Quartet’s 2022 release Between Two Words (Delphian Records), presenting music by Orlando di Lasso, Thomas Adès, Ludwig van Beethoven and John Dowland, was given a double five-star review as BBC Music Magazine’s ‘Album of the Month’: “this outstanding disc offers listeners a true philosophical journey…a series of intricately connected works, each performed with rare beauty and originality by a quartet at the height of its powers…[the Heiliger Dankgesang from Beethoven Op.132] is nothing short of a revelation in its lucidity of line and sheer beauty of sound.”

Formed in 2011, the quartet studied with Oliver Wille at the Hochschule für Musik, Hannover, before being selected by the Young Classical Artists Trust (YCAT) in 2016. They were awarded First Prize at the 2015 Lyon International Chamber Music Competition and in 2018 were recipients of the inaugural Merito String Quartet Award and Valentin Erben Prize, and a prestigious Borletti-Buitoni Trust Fellowship.

The quartet’s 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. Committed to inspiring a diverse audience for classical music, the Castalians have performed everywhere from the great concert halls to maximum security prisons and even the Colombian rainforest. When not on stage, Finnish first violinist Sini Simonen bags Munros, American violist Natalie Loughran mixes mean cocktails and the Welshmen, second violinist Daniel Roberts and cellist Steffan Morris, get overly emotional about rugby.
