The kecak performance takes place on a circular stage, surrounded by bleachers that rise to a maximum of ten feet above ground to give everyone a good view. The performance plays out as the sun sets, and the culmination involves a giant fire display that is integral to the plot. No musical instruments are used in a kecak performance. Instead, you find about thirty bare-chested men sitting in a circle and chanting. The repetitive vocals and costumes is trance-inducing and is described by many as a "trippy experience."
