Gnawa music: Morocco's Asmâa Hamzaoui takes centre-stage

Gnawa music is a Moroccan spiritual musical tradition developed by descendants of enslaved people from sub-Saharan Africa.

Combining ritual poetry with traditional music and dance, the Gnawa master is centre-stage, playing the main guitar-like instrument, the ghembri.

The Gnawa master was always a man in the deeply patriarchal society, but that changed when Asmâa Hamzaoui came on to the scene.

Her father - a Gnawa master - had hoped to pass the tradition of playing the ghembri to a son. But Rachid al-Hamzaoui only had daughters - including one particularly mischievous but talented one.
