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. Their song "Ya Sah" appears in the film The Last Temptation of Christ and on the associated album Passion – Sources.In FilmThe band is the focus of music documentary Transes (Trances), directed by Ahmed El Maanouni, who described Nass El Ghiwane as Morocco's soul music.
