Three elderly Brooklyn brothers reclaim their rightful crowns as “Kings of Klezmer Music” in this joyful documentary about memory, melody, and migration. Living large in the sun-kissed, pre-pressed world of a South Florida retirement community, the Epstein Brothers are the foremost living practitioners of klezmer, the high-velocity folk music that emerged from the villages of Eastern Europe and the slums of New York City. Following the ever-verbose brothers onstage and at home as they entertain retirees or cook matzo balls, bemusedly work a primarily non-Jewish audience in Berlin or look for their father's childhood home in Belarus, A Tickle in the Heart accents the infectious energy of not only klezmer, but the Epsteins themselves. “I play it just the way I would tell a story,” notes one brother about a particular melody; A Tickle in the Heart shows how such songs can tell the stories of a generation.
