The Castalian String Quartet's debut CD, released at the end of April, has received rave reviews.

"Beautifully sprung, precise and detailed" is how their version of Beethoven's late String Quartet No. 15 sounds, says a review in the Guardian. "A compelling reason to buy the disc" is also Thomas Adès' The Four Quarters, Op. 28. "Many quartets have broken the tradition of single-composer discs. The Castalians do it with top performances and meticulous imagination,” is the summary for the recording, which also includes two arrangements by first violinist Sini Simonen: Orlando de Lassus' La nuit froide et sombre and John Dowland's Come, Heavy Sleep open and close the album respectively.
