Bhopa
The Bhopas are the priest singers of the folk deities in Rajasthan state of India. They perform in front of a scroll, known as phad or par in Rajasthani that depicts the episodes of the narrative of the folk deity and functions as a portable temple. The Bhopas carry this phad traditionally, and are invited by villagers to perform in their localities during times of sickness and misfortune. Traditionally, the phads are kept rolled in transit. After reaching a village or town, the Bhopas erect the phads between two poles in a suitable public place shortly after nightfall. The performance goes on throughout the night and terminates only in early morning
