Harlem Quartet’s performances with Cuban pianist/composer Aldo López-Gavilán offer a joyously energetic concert experience. The collaboration reunites López-Gavilán with his older brother, violinist Ilmar Gavilán, who left Cuba at age 14 and went on to co-found Harlem Quartet. López-Gavilán and the quartet showcase scintillating chemistry in a broad variety of repertoire. Programs include American jazz standards, bossa nova classics, and, of course, several original compositions from López-Gavilán that take audiences on a journey through Cuba’s myriad musical traditions. The new documentary Los Hermanos / The Brothers tells the story of Aldo and Ilmar, tracking their shared childhood, their momentous first performances together, and their parallel lives as musicians. A Patchwork Films production by Marcia Jarmel and Ken Schneider, it includes concert footage of the quintet, a genre-bending score composed by Aldo, and guest appearances by such legendary musicians as Joshua Bell. Los Hermanos is screening at film festivals worldwide and will be nationally broadcast on PBS in the fall of 2021.
