Two sisters shake up Morocco’s male-only trance music scene

In the city of Casablanca, two sisters are shaking up a once male-only domain and playing gnawa concerts to global audiences. Their new album, recorded and produced in Sweden, was released recently, and they’ll be touring Europe to promote it this summer. The twist is that it’s their father, a respected gnawa master, who encouraged his daughters to learn the intricacies of this trance music and perform it. Alexa Dvorson reports from Casablanca.
