The founders of Nass El Ghiwane were Laarbi Batma (b. 1948, Oulad Bouziri, Chaouia, Morocco, d. 1998), Boujemaa Hagour, Omar Essayed and Allal Yaala, all of which had experience in music or theatre. Moulay Abdelaziz Tahiri was added to the line-up in the early 70s and Mahmoud Essaadi replaced Tahiri when he quit to form Jil Jilala, although he too would soon join that group. A strong if musically different replacement came with Abderrahmane ‘Paco’ Kirouj. Hagour died in 1974, the group continuing with Batma, Essayad, Yaala and Kirouj in their most stable line-up. The group was the subject of a documentary film, Al Hal (1981). In 1993 Kirouj left to be replaced by Redouane Arif. Laarbi died in 1998 from lung cancer and was replaced by his younger brother, Rachid Batma; later another brother, Hamid Batma, replaced Arif. In the mid-00s, Kirouj was paralysed and unable to continue but the band played on.
