Upstate is an acoustic septet drawing inspiration from every corner (and decade) of America’s musical heritage. Based in New York’s Hudson Valley region, the band has spent years cultivating its sound, and continues to grow by the tune. The instrumentation includes Harry D’Agostino on upright bass, Ryan Chappell on mandolin, Dean Mahoney on cajón, and Christian Joao on flute and alto/baritone saxophone. The dynamic rhythm section supports a three-part vocal harmony powerhouse of founding members Mary Kenney and Melanie Glenn with recent Nashville-transplant Allison Olender. They’ve been an exciting presence at FreshGrass before — we’re thrilled to have them in their mainstage debut at the festival.
