Perhaps the most ebullient “musical” you’ll see this year, Marc-Henri Wajnberg’s singular documentary/fiction hybrid follows a group of street kids—kicked out of their homes for being “witch children”—in the titular Congolese capital. These ever-resourceful youngsters decide to form a band and team up with Bebson, an eccentric impresario and one-time recording star; he’s just one of many unforgettable adults who, whether as informal instructors, fellow musicians, or menacing pursuers, impact the lives of these indefatigable tykes. Completely devoid of sentimentality and condescension, Kinshasa Kids celebrates and honors both the resilience of its young protagonists and the chaotic city in which they live.
