The Weight of Memory closes the inaugural Belvedere Festival with music suspended between radiance, longing, and release. Harriet Steinke’s Too Bright to See opens the afternoon, followed by the haunting song of Chausson’s Chanson perpétuelle. The fierce tango rhythms of Golijov’s Last Round draw the ensemble into motion before Mendelssohn’s exhilarating String Octet brings the festival’s artists together for a brilliant, joyful close.
