"Song & Dance" is an upbeat and heartwarming music documentary that weaves together two powerful stories: the personal journey of Evelyn Keltgen—a girl born with a rare, life-threatening disease who grows up to become a musician—and the rich cultural history of old-time dance bands in the Midwest. Featuring the band Kris and the Riverbend Dutchmen, the film explores legendary ballrooms, unique instruments like the Hengel concertina, and the enduring spirit of polka fans and dancers. With a hopeful eye toward the next generation, Song & Dance is a joyful celebration of family, music, and traditions that refuse to fade.
