With its vibrant lightness of touch and warmth of expression, Rodolfo Halffter’s music is both approachable and stimulating. Volume 3 of this series (volumes 1 and 2 are available on 8.572418 and 8.572419) brings his complete string quartets, each with its own power and expression, exploratory intellectual curiosity and impish wit. The composer’s only Cello Sonata inhabits a world of neoclassical refinement with hints of Hispanic rhythm and melodic gesture, and Halffter’s Spanish/Mexican idiom is second nature to the Madrid based Bretón Quartet.
