"In December 2024, the Dallas Jewish Historical Society had the profound honor of presenting Heather Klein’s Shanghai Angel—a soul-stirring musical that brought tears, hope, and remembrance to our community. Through hauntingly beautiful Yiddish melodies and deeply personal storytelling, Klein shared the extraordinary journey of her grandmother, Rose Ginsberg, who fled Nazi-occupied Vienna and found refuge in Shanghai. This performance was more than a musical—it was a living memory, a tribute to courage, survival, and the enduring strength of family. It reminded us that even in the darkest times, the human spirit can sing.”

— Beri Schweitzer, Dallas Jewish Historical Society

"Her musicianship and command of Yiddish repertoire are clear contributors to her magnificent style."
