The Stein family gathers on Manhattan’s Upper West Side to celebrate an engagement. But when their youngest son arrives with an unexpected guest, the joyful occasion begins to unravel—revealing old wounds, buried secrets, and divisions that may be impossible to overcome. As a mysterious blue violinist watches over them, three generations must confront what it means to remain a family when the people they love no longer see the world in the same way. Inspired by the spirit of Sholem Aleichem’s Tevye, The Blue Violinist Over West End Avenue is a funny, provocative, and deeply moving new play about family, faith, identity, and the enduring—and sometimes fragile—power of love.
