Shostakovich and Mendelssohn had much in common: both were child prodigies, both left behind a vast body of work, both were fantastic pianists, and both were capable of plumbing the depths of the human psyche. Shostakovich’s piano quintet combines soul-searching and sweetness, while Mendelssohn’s D minor Trio begins in restless disquietude but ends in triumph. Opening the program is J. C. Bach’s G major Flute Quartet, a lovely work that bridges the gap between Baroque and Classical music.
