Moroccan group Innov Gnawa performs the first of Bang on a Can’s concerts as part of the summer music series Artists at Noguchi. Innov Gnawa is a young musical collective dedicated to exploring Morocco’s venerable gnawa music tradition. Gnawa music is the ritual trance music of Morocco’s black communities, originally descended from slaves and soldiers once brought to Morocco from Northern Mali and Mauritania. Often called “The Moroccan Blues,” gnawa music has a raw, hypnotic power that’s played on an array of unique instruments.
