Nass El Ghiwane are a musical group established in 1971 in Casablanca, Morocco. The group, which originated in avant-garde political theater, has played an influential role in Moroccan chaabi (or shaabi). Nass El Ghiwane were the first band to introduce Western instruments like the modern banjo. Their music incorporates a trance aesthetic, reflecting the influence of local Gnawa music. Khaled, a prominent Raï singer, began his career performing Nass El Ghiwane songs at weddings and parties. They are also credited for helping bring a new social movement to Morocco.
