Few violinists can move between a modern instrument and a period one with such ease—not to mention with such an idiomatic approach to so many styles of music—as Isabelle Faust. Following her award-winning set of the Mozart violin concertos, the German is joined by the ever-stylish keyboard player Kristian Bezuidenhout for Bach’s sonatas for violin and harpsichord. Both instruments sound magnificent, and these two great players bring breathtaking invention and imagination to the six sonatas. The humanity and warmth of Bach’s music is extraordinary, especially when played with the passion and flair encountered here.
