The caliber of the Nishizaki-Loeb partnership is outstanding. They provide expressive playing that is light and delicate. Their performances overflow with imagination and a high degree of intimacy. Nishizaki is highly experienced and has sold possibly the most recordings of any violinist. She has the advantage of a technique that is comfortably secure with a pleasing tone that is crisp and cool. There is a purity to her playing, fused with a relaxed manner that is hard to resist. The elaborate piano part in the hands of Loeb is natural and unforced. The duo's choice of speeds tends to be rather on the slow side for my taste. However, in the allegro of K570 (track 6) the players demonstrate that they can quicken when they choose. I especially enjoyed their sensitive performance of the adagio of the Sonata K570 which is tender and highly compelling. Also impressive is the closing movement rondo of the same Sonata, dazzlingly played with joy and vitality, and totally free of affectation. Something special is also happening in the Sonata, K403 at several points in the allegro - allegretto (track 4) especially at points 1.27-2.11; 3.30-4.09 and 5.18-6.26 where the unison playing is exceptional.
