Fima Chupakhin is a jazz pianist from Ukraine. For the past 10 years, though, he’s been living in New York City. Chupakhin hasn’t been back in Ukraine since Russia’s full-scale invasion, however, he’s been a staunch advocate for his home country. In fact, if you’re a Ukrainian musician visiting New York for a fundraising concert or any other advocacy event, you’ve probably met or even performed with Fima Chupakhin.
