The New York City-based Chelsea Symphony will perform “Remembrance” concerts on October 29 and 30 featuring two works composed in remembrance of those we have lost. Tim Kiah’s new work, Our Dear Friend, remembers Kurt Behnke, a longtime Chelsea Symphony cellist who died of COVID. The series also features the world premiere of Kamala Sankaram’s viola concerto 91919 with viola soloist Brian Thompson, described as a “moving meditation on grief.” Also on the program will be Schubert’s “Unfinished” Symphony, said by some scholars to be inspired by personal trauma; Saint-Saëns’ Suite for Cello and Orchestra with soloist Violet Wang; Lars-Erik Larsson’s Trombone Concertino with soloist Morgan Fite; and Arvo Pärt’s Fratres with violin soloist Veronica Riner. Reuben Blundell and Matthew Aubin will conduct the concerts at St. Paul’s German Lutheran Church in Manhattan.
