The group's "Trances" are our equivalent of "soul music", our irrationality. I followed the example of the Nass El Ghiwane themselves: I went back to the roots. They draw their music from the last thousand years of Moroccan and African history. the film sets out to reveal and emphasize this heritage. I chose the music of the Saharan brotherhood, The Gnawas, and the verses of the famous poet El Mejdoub, to underline the trances.
