Arthur Grumiaux and Walter Klien offer playing with spring in its step and a lyrical yet unsentimental warmth in the slow movements, though that of K296 might with advantage have lingered a little more. These are stylish artists who are also eloquent in the unusually wistful Andante con moto of K380 ... Perhaps a touchstone for Grumiaux's qualities is the great slow movement of K454, where he is sensitive to the extraordinary harmonic design and yet over-reliant on the same tricks of tone-colour to project it. -- The Gramophone Magazine
