In 2016, they took home a Royal Philharmonic Society Award for their performances of cycles of the complete Shostakovich Quartets. This Shostakovich15 project was accompanied by a recording of quartets 4, 8 and 11 for Signum Classics, to which the quartet added a further volume in spring 2019 (1,2 and 7) acclaimed by Gramophone Magazine for its '…athletic, upfront performances, clear in texture, forthright in tone and bold in articulation.'

The quartet has released a bevy of acclaimed recordings on their own label, Carducci Classics, as well as Signum Classics, and their Naxos recordings of Philip Glass Quartets have had over six million plays on Spotify.

Sarah Williamson, is renowned as a virtuoso clarinettist whose talent has been recognised by concert-goers and critics alike.
