More than than 100 young musicians from the Boston Youth Symphony Orchestras are taking part in this one-time event bringing to life a dark tale of drama, selfishness and rejection – an opera in three acts based on the eponymous novel by Alexander Pushkin.

This semi-staged production will be sung in Russian with English supertitles. Among the young musicians performing Sunday are Cantabrigians Mai Nguyen, 15, and Ina Suresh, 17, both flutists; and Sun-Jung Yum, 15, playing viola. Longtime Cantabrigian Catherine Weiskel is the orchestra’s executive director. Information is here.
