In Kano City, Northern Nigeria, crowds gather to watch local heroes face off in the ancient Hausa martial art of Dambe. Part battle, part dance, part live mythology, it’s a cultural tradition that has survived and thrived in the region, despite invasion, famine, British colonialism and attacks by Boko Haram. In Dambe’s lightning-fast bouts, against a hypnotic soundtrack of live drumming and improvised praise songs, conflicts erupt, rivalries are formed and legends are made.
