The zemutara music tradition is a music tradition practiced by rakian spice users in the ancient spice empire. Zemutara music is used to produce trance effects after partaking of rakian spice, during which time practitioners experience lucid visions of the future. Practitioners then believe themselves capable of influencing future events. The zemutara tradition, along with rakian spice addiction and rakian spice psychosis, are believed to be partly responsible for the collapse of civilization in that area of the galaxy known as the ancient spice empire, located in the unknown regions.
