Harold López-Nussa is a 35-year-old jazz pianist and composer from Havana, Cuba. He’s traveling the world promoting his new album. Nussa’s tour includes a stop in the Berkshires Saturday night, when he’ll take his vibrant piano-driven sound to Club B10 at MASS MoCA. WAMC spoke to Nussa about his musical origins, the culture of jazz in Havana, and what it feels like to bring the people of Cuba and the United States together through music.
