TANAH LOT, Indonesia (Reuters) -- About 5,000 people danced in a trance outside a Balinese temple on Friday in a colossal show aimed at reviving the Indonesian island's tourism industry, still feeling the pinch of last year's deadly bombings.

The Kecak dancers, dressed in checkered black-and-white sarongs, raised their arms and chanted "Cak Cak Cak" in a frenzied chorus at the foot of the grand Hindu Pura Tanah Lot temple overlooking the sea, just as the sun went down.

A Kecak performance traditionally involves between 75 and 100 people, and organizers said a performance on this scale was unprecedented.

"The event is aimed at reviving the spiritual, cultural and economic aspects of Balinese life," the local government, which organized the show, said in a statement.

About 5,000 people, including former president Megawati Sukarnoputri and many foreign tourists, watched the performance dubbed "Cakolosal 5000" from a specially constructed platform.

Muslim, Christian, Hindu and Buddhist religious leaders offered prayers for peace before the performance began under tight security and the show ended with a spectacular fireworks display.

"It was very enjoyable. It's good for Bali's tourism recovery," said a spectator.

The Kecak is among the most dramatic of Balinese dances. Rooted in the so-called sanghiang trance dance and drawing on elements from the Hindu epic Ramayana, it is a mix of theatre, music and dance.

Tourism in Bali, a predominantly Hindu region in mostly Muslim Indonesia, is still struggling to recover one year after three suicide bombers blew themselves up at three restaurants in October last year, killing 20 people.

These attacks came three years after Islamic militants bombed two Bali nightclubs, killing 202 people, mostly foreign holiday makers.

The attack were among a series of deadly bombing attacks in recent years blamed on Islamic militants from the Jemaah Islamiyah militant group.

The number of foreign tourists visiting Indonesia fell 10 percent in July from a year ago, the statistics bureau said last month, as security concerns and disasters from bird flu to earthquakes kept visitors away.
