How can you go wrong when three of some of the most talented classical performers come together to play Mendelssohn? Pianist Emanuel Ax (who performs regularly with Ma) gives the music an earthly foundation before taking flight with the cello and violin. While not a crossover star like Ma and Perlman, Ax stands up to their talents. This is a ravishing set, but also a playful one -- the joy the trio experiences while playing is transferred to the listener. Artistic alchemy.
