The Ganga are an ethnic group of African descent living in Perico, Matanzas, Cuba. They were taken to the Caribbean island as slaves from the nowadays Sierra Leone, within the Dahomey region. In this region, the most revered saint was Babalu Aye (named by Yorubas like that), Yebbé called by the Ganga.
After the syncretism that slaves nedded to worship their deities without Spanish repress, Yebbé is sincretized with San Lazaro.
On December 17, the day of San Lazaro, is the only day of the year that Ganga drums sound, and they only sound in Perico, because it is the last Gangá family left in Latin America, and perhaps in the world ... That day, they sing, play, dance, eat, drink and make offerings to Yebbé, the saint revered by Ganga.
