Each member of this very classy group is a magnificent Brahms player. Put them together and real magic happens. Brahms’ three trios span his creative life—No. 1 was completed when he was 20 (later revised, as played here), and Nos. 2 and 3 were composed while he was in his late ’40s and early ’50s. This is chamber music-making of a superior order: flexible, full of insight, joyful and captivating in its freshness. Kavakos, the youngest of the trio, partners the two long-time friends with an innate and heart-warming sense of style.
