Founded in 2019, the Keystone Quartet continues to captivate audiences across the United States with fun, inspirational, and educational music. United by a shared passion for showcasing the tuba and euphonium, our quartet is committed to expanding the repertoire through commissioning new works and creating engaging projects for diverse audiences. In Spring 2022, we released our debut album, Sweet Appalachia, featuring a full disc of original compositions crafted for tuba-euphonium quartet. Following its success, we proudly launched our second album, Keystone Kitchen, in May 2024, now available for streaming on major platforms.
