This is an amazing set of grim, often bizarre music. The Trio No. 2 is a lament for the Russian Jews killed during World War II. The late Violin and Viola Sonatas sound like laments for the composer himself, in ill health and nearing the end of his life. Even the Cello Sonata, composed in slightly happier times, is far from humorous. Only the one-movement First Trio, a strange piece, has much happiness in it. If you"re ready to face this difficult music, though, these performances by splendid musicians bring everything to life, and the "twofer" set is a great deal. --Leslie Gerber
