The Big Mountain Music Festival returns to Bonanza Khao Yai Resort in Nakhon Ratchasima for a fourth time on Dec 8-9.

For an idea of what should be Thailand's biggest and best mountain music festival, just stop by CentralWorld, host to a photo exhibition from tomorrow to Nov 11 showcasing the high points of three previous festivals.

On show are hundreds of pictures taken by professional photographers and festival-goers. The aim is to give first-time visitors an insight into the atmosphere associated with the festival, and old fans an opportunity to recollect the good times they've had together.

Since its inception in 2010 and the two subsequent events, the festival has drawn in more than 100,000 visitors to the mountain resort of Khao Yai.
