Recorded between 1989 and 2004, the Hagen Quartet's recordings of Mozart's complete music for string quartet is clearly the finest set of the works released in the early digital age. For one thing, because the collection includes not only the 23 canonical string quartets but also the three early Divertimenti for string quartet, the five Fugues from Bach's Well-Tempered Clavier arranged by Mozart, and the late Adagio and Fugue in C minor, their set really is the complete music for string quartet.

Hardly any combination of instruments is more appealing than a string quartet and a clarinet; together they make a magical melange. The Hagen Quartet and Jörg Widmann have recorded Mozart's Clarinet Quintet, a "work among friends", in this irresistible blend. Jörg Widmann, clarinettist and composer in equal measure, picks up on the omnipresent themes of "floating, love, and chant" in Mozart's notes and creates a weighty counterpart to Mozart's popular work with his own clarinet quintet, which is available here in a world premiere recording.

In its 2012/13 season, the Hagen Quartett brings the complete Beethoven string quartets to the most prominent musical centres of the world, including New York, Tokyo, Paris, London, Vienna and Salzburg. During the first half of this tour, the quartet went right away from the stage to the studio to record three of their most favourite Beethoven quartets. With Op. 18/3 and Op. 135, the album ranges from the very first to the last string quartet Ludwig van Beethoven wrote.
The Hagen Quartet came into being in 1981, soon achieving success in a number of competitions and signing an exclusive recording contract with DG, which over the course of a 20-year relationship produced 45 CDs.

This album marks a milestone in the extensive discography of the Hagen Quartett – myrios classics is honoured to present their first recording of a Brahms string quartet. The quartet op. 67 is paired with Brahms’ piano quintet op. 34. Here, the Hagen Quartett is joined by their regular collaborator, pianist Kirill Gerstein.

The gentle melancholy of the "Trout" quintet is beautifully realized here by Andras Schiff and members of the Hagen Quartet. The final two movements almost seem to be one longer movement with a unity of expression between them that is most compelling, to the extent that the themes of the final movement have the feel of being further-flung variations of the "Trout" theme itself. The lower strings are particularly effective in these movements, and Schiff's lucid and un-plushy Bosendorfer sound is ideal. The earlier movements had the feel of a Dumka before Dvorak, with their alternation of more assertive and more quiet sections – but it's the melancholy character that wins out and gives this performance its particular force.

Das Hagen Quartett ist ein in den 1970er Jahren gegründetes Streichquartettensemble aus Salzburg und gehört zu den führenden Streichquartetten der Welt. Bekannt wurde das Hagen-Quartett besonders durch seine Gesamteinspielung der Streichquartette Mozarts.

The ensemble's latest recording of Mozart string quartets left critics agog: "I doubt that these particular works have ever been recorded with such astonishing command as by the Hagen Quartett. The players' corporate intonation is almost impossibly true . . . A disc whose rare brand of perfectionism is rather special." (CD review by Julian Haylock, The Strad)

Beethoven's second set of quartets, Opus 59, inhabit a very different universe from that of his first set, Opus 18. Although only six years had passed since the publication of the Opus 18 quartets, Beethoven's style changed immensely. The Opus 59 quartets were composed in the wake of the "Eroica" Symphony, and the vastness of the individual movements; the symphonic, orchestral character of the string writing; and the stretched formal boundaries led some critics to dub the first of the set an "Eroica" for string quartet.

“By far the most compelling interpretation of Mozart’s string quartets comes from Salzburg: there is scarcely any other group that is capable of covering the vast stylistic range of these works as convincingly and as vitally as the Hagen Quartett. The result is a recording that should still be valid in thirty years’ time.” (Neue Zürcher Zeitung)

Few chamber works rise to the autobiographical level achieved in the two string quartets of Leos Janácek. The First Quartet, subtitled "Kreutzer Sonata," depicts scenes from the novel of the same name by Leo Tolstoy and tells the story of an adulterous wife and her resulting death at her husband's hand. Janácek himself was locked in a loveless marriage and found many parallels (without the homicide) in his life. The Second Quartet, "Intimate Letters", draws inspiration from the unrequited love affair the composer had with Kamila Stosslova and the hundreds of passionate letters he was to write to the woman half his age.
