A charismatic stage performer who crisscrossed the world and was feted by princes, sultans and czars; a diva activist who confronted totalitarianism and despotism with her music; an internationally acclaimed artistic pioneer who sang in 24 languages and was the first woman to bring Yiddish songs to the world's concert stages, Isa Kremer has been almost forgotten. Until now. This fascinating documentary recovers her remarkable story through a wealth of archival footage and photos as well as interviews with family members, friends, and performing artists. In reclaiming Isa for posterity, the film takes us from her earliest years in pre-Revolutionary Russia through an eventful personal and professional life in Europe, the United States, and South America where it was inextricably linked with five turbulent decades of twentieth-century history. This multifaceted portrait of a complex, passionate woman bridges a vanished past and a continuing legacy that transcends both borders and time.
