Winner of the First Prize at the 2015 Lyon International Chamber Music Competition, the Castalian String Quartet is fast becoming a favourite with audiences in the United Kingdom and abroad for its 'richly romantic energy and passion' (Strad Magazine). In May 2016, the quartet is nominated « 2016 YCAT Artists (Young Classical Artists Trust) ».

Formed in 2011, the Castalian String Quartet has been the beneficiary of awards from the Royal Overseas League (2011 Elias Fawcett Trust Award), the Countess of Munster Trust, the Tunnell Trust, the Royal Philharmonic Society, St. Peter's Eaton Square, Kirckman Concert Society and Mozarteum de France.

In 2013, the Castalian String Quartet won both the Audience Prize and First Prize in the Kammermusik Hannover Next Generation Competition, broadcast on German radio station NDR. In September 2016, the Quatuor won the Banff International String Quartet Competition (BISQC) third prize. 

Highlights from previous seasons include performances at the Wigmore Hall, the Purcell Room, Kings Place, Lake District Summer Music, the Edinburgh Festival and a BBC Radio 3 recital from the Cheltenham Festival. The quartet also toured China at the invitation of the British Council.

2014 brought the release of the quartet's recording of Mendelssohn on the Champs Hill label (awarded BBC Music Magazine's 'Critic's Choice' for September, and 'Chamber Music Disc of the Quarter' by the German Record Critics Association).

In 2014 they graduated from the Hannover University of Music, Dance and Theatre with a Masters Degree in Chamber Music, studying with their mentor Oliver Wille. The quartet has also worked closely with Thomas Brandis and Levon Chilingirian.

During the 2015-2016 season, the Castalian Quartet participates in a young composers project in Paris, in partnership with ProQuartet and Paris Conservatoire Composition Class.
