The Masters’ performances feature a dancer dressed as Bou Jeloud, a Pan-like figure half goat half man. Although the character of Bou Jeloud is found all over Morocco, it takes on  different form in Joujouka.
In Joujouka, Bou Jeloud gave an Attar ancestor the gift of flute music and bestowed fertility on the village every spring when he danced. The music relating to this is the Masters at their most mind-blowingly powerful.
