This series presents chamber music in three uniquely impactful instrumental configurations. Two of today’s finest string quartets—the Belcea Quartet and Quatuor Ébène—join forces in quintessential string-octet compositions by Felix Mendelssohn and Enescu. Revered pianist Emanuel Ax and leading clarinetist Anthony McGill perform a wide-ranging program in their first-ever duo concert at the Hall. The esteemed Tetzlaff Quartet treats listeners to Dvořák’s final chamber work, Jörg Widmann’s dynamic “Choralquartett,” and Felix Mendelssohn’s String Quartet in A Minor.
