Enjoyable as other digital recordings of Beethoven's first quartets are, this new Tokyo set just about pips all rivals to the post. The reason is primarily one of balance, not only within the group itself but also in terms of overall musical judgement – whether relating to tempo, dynamics or emphases, or simply the way the players combine a sense of classical style with an appreciation of Beethoven's startling originality. If you're after a top-ranking digital set of Op 18, you couldn't do better.

Founded in 1969 at the Juilliard School of Music, the Tokyo Quartet have amassed a fine and distinguished array of recordings for various labels, many enthusiastically received. In 2013 they disbanded after their longest serving members, the second violin Kikuei Ikeda and viola Kazuhide Isomura, decided to retire. Their final concert took place in Norfolk, Connecticut on 6 July 2013. For the last ten years of their existence, they were contracted to the Harmonia Mundi stable.

These quartets, Haydn's last great quartet collection, represent a peak of musical achievement that may have been equaled, but has never been surpassed. Haydn invented the string quartet way back in the 1750s, and by the time he came to write these works some 40 years later, his mastery was so natural and effortless that it's hardly noticeable. All you hear are the great tunes, dramatic surprises, fresh rhythms, and ever-new string textures. These immaculate performances by the Tokyo Quartet went a long way toward establishing it as one of the most exciting young string quartets to emerge in the past two decades, and they have been superbly recorded. A classic set, then, and essential listening.

First released in 1991 and reissued in 2004, this CD of Mozart's Clarinet Concerto and the Clarinet Quintet is fair in most regards except for the featured soloist's quirky playing. Richard Stoltzman's fans may like this disc in spite of its problems, especially if they are more interested in clarinet technique than in Mozart's music. But others may sense that he has little understanding of the composer or Classical style, and that these interpretations are superficial and whimsical, rather than deeply felt or carefully considered.

The eighteenth century is probably the most extraordinary period of transformation Europe has known since antiquity. Political upheavals kept pace with the innumerable inventions and discoveries of the age; every sector of the arts and of intellectual and material life was turned upside down. Between the end of the reign of Louis XIV and the revolution of 1789, music in its turn underwent a radical mutation that struck at the very heart of a well-established musical language. In this domain too, we are all children of the Age of Enlightenment: our conception of music and the way we ‘consume’ it still follows in many respects the agenda set by the eighteenth century. And it is not entirely by chance that harmonia mundi has chosen to offer you in 2011 a survey of this musical revolution which, without claiming to be exhaustive, will enable you to grasp the principal outlines of musical creation between the twilight of the Baroque and the dawn of Romanticism.

The Tokyo Quartet became one of the most prominent string quartets in the world and continues a reputation for insightful interpretations.

The Tokyo quartet plays with very much sense of the architecture of the music. If you like your Beethoven played with restraint, refinement, sense of the interior drama of the music, this is it. The Tokyo quartet is never over-dramatizing, but let the music speak for itself.

These recordings of Beethoven's early quartets are excellent. The Tokyo String Quartet's technique has never been in doubt and needless to say, just as all great string quartets, the members are perfectly synchronized, playing together as one, as if controlled by a single mind.

The Tokyo String Quartet is one of the world's leading interpreters of Beethoven, and although its 1993 RCA release of the complete string quartets is one of the most admired of modern digital sets, the ensemble offers a refreshed presentation of the late string quartets on this 2010 triple SACD package from Harmonia Mundi. This release follows albums of Beethoven's early and middle quartets, issued by the group between 2005 and 2009, and while the Tokyo's personnel differs from past lineups, the group has maintained great consistency of tone, superb technique, and refined expression since its founding in 1969.
