"On stage, Jim underwent a complete metamorphosis: his soft gentle voice became raspy, husky, deep and powerful; his slouchy stance became arrogant, proud; his placid face turned into a thousand masks of tension and emotion; and his eyes, usually so penetrating and searching, turned vacant, glazed over and stared out at the audience like two bright windows.
He made strange animal sounds, screamed and cried out as if in pain. His leather or snakeskin clothes crinkled and groaned as he moved. His movements and gestures became fitful and spasmodic, like a person in seizure. He danced, not with gracrful and fluid motions, but with short hopping steps and piston like motions, bent forward, head snapping up and down. He moved like an American Indian performing a ritual dance.
On stage, Jim became the shaman."
Frank Lisciandro from JIM MORRISON: An Hour For Magic

In the seance, the shaman led. A sensuous panic, deliberately evoked through drugs, chants, dancing, hurls the shaman into trance. Changed voice, convulsive movement. He acts like a madman. These professional hysterics, chosen precisely for their psychotic leaning were once esteemed. They mediated between man and spirit-world. Their mental travels formed the crux of the religious life of the tribe.
