And then Mame Khan starts to sing, the melody aimed across the desert, carrying on the wind without need of amplification. Ghamse Khan&rsquos bow traces the voice on his kamaicha, the strings yielding a sound that seems like the desert distilled. And when their notes have laid down a shimmering path in the air, Shafi Khan&rsquos khadtaal and Roshan Khan&rsquos dholak join in. Virtuoso playing brings to life uncommon songs about rites of passage, praise for a patron, the story of a saint who brought a child back from the dead. This is western Rajasthan&rsquos cultural memory, the Manganiar its guardians. His late father Rana Khan is counted among the great Manganiar singers and Mame Khan must keep his legacy alive. The future of their tradition is present this evening in the form of Dayam Khan and Roope Khan, tiny boys under oversized turbans, looking up intently at their fathers&rsquo and uncles&rsquo faces, singing their heart out when it is their turn.
