National Geographic Music (National Geographic)

Known collectively as "the Moroccan Gypsies" these itinerant musicians from Morocco are actually two troupes—Groupe Sidi Mimoun with Abdenbi El Gadari and the group Ben Souda with Taïfa-Al Essawiya— that are the most impressive examples of the living tradition of North-African Roma, or Gypsy music. Their music is distinguished by call-and-response singing accompanied by the mighty bass gimbri (a 3 stringed bass lute) and the earthy sound of the qraqabas (metal cymbals), as well as many other indigenous Moroccan instruments.
