Virtuoso Afro-Cuban-born brothers—violinist Ilmar and pianist Aldo—live on opposite sides of a geopolitical chasm a half-century wide. A thaw in the US-Cuba relations offers the first opportunity for the brothers to tour the US together. But at the tour’s end, politics shift again, threatening the brothers’ dreams. Tracking their parallel lives in New York and Havana, their poignant reunion, and their momentous first performances together, Los Hermanos/The Brothers offers a nuanced, often startling view of estranged nations through the lens of music and family.
