n extraordinary documentary that follows the rise of Staff Benda Bilili, from the poverty stricken streets of Kinshasa to European acclaim, on the back of a debut album. The band of disabled Congolese musicians and street children, play conventional and improvised instruments. The group’s original core is made up of three middle aged polio surviving street dwellers, who sleep on cardboard boxes in the slums of the city, where they stay human by making music. Their star is Roger Landu, plucked off the streets when he was just 12. Roger, who is non-disabled, plays a curious self-invented instrument which consists of an empty tin, a curved piece of wood and a tightly stretched string, from which he extracts tuneful solos.
