Shock 'Em Dead 1991 ( 4.3)

Martin is a total loser, who nobody cares for. When he fails to get a position as guitar player in Lindsay's band and loses his job on the way, he makes a deal with a Voodoo priestess. She promises him the fulfillment of all his dreams if he swears obedience to her. He becomes a rock star and has many women - but to stay alive, he has to kill other people.
