”The best of Saturday was saved to last with a scorching performance of the third Razumovsky quartet by Opus13 in Crail. This young Scandinavian quartet made their UK debut at the 2024 festival and they have gone from strength to strength since. Hearing the airborne freedom with which they phrased Beethoven’s melodies, the searing commitment of their playing and their breathtaking virtuosity in the hell-for-leather finale, you can see why.”

"Such is the intensity in their response to the score that at times it feels like we’re listening to a chamber orchestra, not a quartet."  "Disciplined ensemble, a fresh, distinct sound unadorned by deference or convention, and an appealing kind of youthful ardour. It’s bounded energy that emanates from the stage. Evident attention to detail, joy sought in playing together. There’s a sense they’ve brought fresh air to the stage. Their difference is noticeable."

"Of the three Op.59 quartets, the 3rd has the only first movement that is pure fun and free of angst, and Opus13’s technical mastery made sure that was how we experienced it, right up to its whimsical accelerating coda."

— Edinburgh Music Review, July 2026

"Then to the last Rasumovsky, and a performance that had us clinging to the edge of our seats. It opened with bristling resolve, struck a graceful balletic note in the Andante con moto, before viewing the unruffled Minuet as an understated springboard to the final fugue, a hair-raising sprint to an explosive conclusion."

— Vox Carnyx, July 2026

"...their playing here was revelatory: freewheeling, carefree and delightful, flying high but without the aid of a safety net. Even the genteel Minuet seemed to have an arch eyebrow raised, and they attacked the hell-for-leather finale with such energy that I half expected to see sparks flying from their bows. The audience positively roared its approval at the end, which isn’t something Crail sees very often."
