Pablo Casals and Rudolf Serkin were titans of their instruments, and their Beethoven cello sonatas document one of the great musical partnerships. The three sonatas here span Beethoven's compositional life, growing ever more ambitious and intimate. Casals brings warmth and nobility to the cello line while Serkin provides both support and sparkling counterpoint. These 1989 recordings capture the pair in repertoire they had played for decades, bringing a lifetime of understanding to bear. Essential chamber music for any serious listener.
