The third volume of the Danish String Quartet’s ongoing Prism series, which shows how the radiance of Bach’s fugues is refracted through Beethoven’s quartets to illuminate the work of later composers. “Beethoven had taken a fundamentally linear development from Bach,” the Danes note, “and exploded everything into myriads of different colours, directions and opportunities – much in the same way as a prism splits a beam of light.” Here the quartet follow the beam from Johann Sebastian Bach’s Fugue in c-sharp minor through Ludwig van Beethoven’s String Quartet no.14 to Bela Bartok’s String Quartet No.1. “A revelatory connected soundscape in which Beethoven’s introspection feels more unsettling than usual.” – BBC Music Magazine on Prism II “It’s natural music-making…..” – Gramophone Magazine on Prism II

For its third ECM release, the Danish String Quartet inaugurates a series of albums with the overarching title of Prism, in which the group will present one of Beethoven’s late string quartets in the context of a related fugue by J.S. Bach as well as a linked masterwork from the quartet literature.

With Prism 1, it is the first of Beethoven’s late quartets, his grand Op. 127 in E flat major, alongside Bach’s luminous fugue in the same key (arranged by Mozart) and Dmitri Shostakovich’s final string quartet, No. 15 in E flat minor, a haunted and haunting sequence of six adagios. The DSQ recorded the disc at the Reitstadel in Neumarkt, Germany, applying its lyricism and spirit of ensemble to the interconnected sound world of these three composers.

Hailed by the Washington Post as “one of the best quartets before the public today” and as simply “terrific” by The Guardian, the Danish String Quartet is now one of the world’s leading string quartets. In 2009, the DSQ took First Prize, plus four additional prizes, in the Eleventh London International String Quartet Competition. They also received the Carl Nielsen Prize, Denmark’s most important cultural award, in 2011. The group’s 2017 ECM album, Last Leaf, saw it explore the texturally rich, emotionally resonant world of Nordic folk music.

They are widely recognised as the most exciting young string quartet of the present moment, bringing new insights to contemporary composition and core classical repertoire. In parallel, they have also made surprising and impressive forays into the world of Nordic folk music. Their 2014 album Wood Works (Dacapo Records) was a left-field hit, and audiences around the world have been delighted by concert performances of the music. Now the Danish String Quartet bring their folk project to ECM with a stirring new recording. Fästan takes off from an unusual Christmas hymn, “Now found is the fairest of roses”, published in 1732 by Danish theologian and poet H.A. Brorson. The hymn is set to a mysterious, dark melody: Brorson had chosen an old Lutheran funeral choral to accompany his Christmas hymn, elegantly showing how life and death are always connected. “From here we embark on a travel through the rich fauna of Nordic folk melodies until returning to Brorson in the end,” say the DSQ. “It is a journey that could have been made in many different ways, but we believe that we returned with some nice souvenirs. In these old melodies, we find immense beauty and depth, and we can’t help but sing them through the medium of our string quartet. Brorson found the fairest of roses, we found a bunch of amazing tunes – and we hope you will enjoy what we did to them.”

This is the Danish String Quartet’s fourth instalment in the Prism series, the group’s ongoing project that will ultimately hold five volumes of recordings linking Bach fugues with Beethoven quartets and quartets by alternating later composers. While the preceding volumes presented quartets by masters who lived to experience the 20th century – these being, in order of their appearance in the series: Dmitri Shostakovich, Alfred Schnittke and Bela Bartok – Prism IV finds the Danish musicians interpreting Felix Mendelssohn’s (1809-1847) String Quartet No. 2. As Paul Griffiths remarks in the liner notes, the quartet’s interpretation of Mendelssohn is empowered by Beethoven’s model in terms of “vivid gesture, contrapuntal energy, harmonic boldness and formal innovation”. The piece is paired with Beethoven’s String Quartet No. 15 and Bach’s Fugue in G minor, BWV 861 in the arrangement of the Austrian educator and composer Emanuel Aloys Forster.

The Danish String Quartet bring their highly acclaimed Prism project to its conclusion. In each volume of this series a particular Bach fugue is connected to a late Beethoven quartet which, in turn, is connected to a quartet by a later master: “A beam of music is split through Beethoven’s prism,” in the Danes’ words. “The whole approach invites active, committed listening,” The Guardian observed. “The group plays with virtuosity, intensity and tenderness.” The project has been eight years in the making. Now on the fifth and final volume, Johann Sebastian Bach’s chorale prelude Vor deinen Thron tret ich hiermit “opens up like a flower”(as Paul Griffiths writes in the liner notes)topreface Ludwig van Beethoven’s String Quartet No. 16 in F major. Anton Webern’s early String Quartet, composed in 1905 – and inspired both by Beethoven and Schoenberg – follows, and the programme returns to Bach with Contrapunctus 14 from The Art of the Fugue.
