The playing in these endlessly fascinating and rewarding pieces is supremely accomplished. Distinguished Bartók cycles in recent years include those by the Alban Berg (EMI), Emerson (DG) and the Takács Quartets - but none more vividly conveys the music's visceral excitement.

Bartók's quartets are one of the great musical collision points between modernism and romanticism.
How to handle the tension between their expressive gestures and constructivist designs is one of the abiding issues for performers and one reason why even the plethora of fine available recordings cannot remotely exhaust their riches. Getting the best of all worlds interpretatively is hardly a realistic aim. Even so, there are long stretches where the Belceas come as close to the ideal as any ensemble on disc.
Try the first few minutes of Quartets Nos 2 and 3, and marvel at the gradation of forte and fortissimo, of piano and pianissimo, which helps to give entire movements far more convincing shape than less precisely observant ensembles achieve. Try the outer movements of No 5 and marvel at the gear-changes negotiated smoothly, instantly and unanimously, yet never as ends in themselves, always accompanied by a sense of expressive-dramatic purpose. Try virtually every movement in fact, and revel, as the Belceas do, in the interplay of the lines, even in passages where others seem thankful just to come through unscathed.
Clearly immense thought has been given to tone quality. In the first movement of No 1, for instance, the Belceas point the periodic arrivals on consonant harmonies by withdrawing vibrato, and instantly the as yet not fully mature Bartók's straggly structure gains sharpness of profile.
They apply the same ploy in the much tauter environment of the first movement of No 5, and with similarly revelatory results. At the other extreme, their sustained tonal intensity makes the most barbaric onrushes exhilarating rather than exhausting, neither too streamlined nor too effortful. When the score is bare of instructions, as in the first slow movement of No 5, they take it at its word and uncover a hypnotic, staring blankness. And when the invitation to humour is extended, as in the finale of the same quartet, they seize it with full-blooded, yet never selfserving, relish.
Before surrendering to the power of these performances, one wondered if there was going to be enough ethnic tang and zest, enough wildness and strangeness, enough sultry longing.
We've certainly heard more of those qualities in the first two quartets. Yet the central movement of No 2 is marked molto capriccioso, not barbaro, and that's exactly what comes across, while the coda is pushed daringly close to the edge, sounding like the distant fluttering of giant moths – not as precisely by the book as the Emersons but vastly more imaginative and emotionally telling – while the slow finale has a superbly intense accumulation at its heart.
Pushed for a general reservation, perhaps when a 'speaking' quality is needed in the quasirecitatives, the first violin's colleagues don't quite match her for idiomatic insight. And do the Belceas get to the heart of the matter in the trauma-shaded No 6? Not quite – not by comparison with The Lindsays, anyway, who are generally more prepared to tolerate rough edges for the sake of emotional revelation.
In short, the Belceas are more than worthy rivals to the best on disc and EMI's recording quality is just right.
