Sweaty nightclubs with their slippery dancefloors are pretty much the norm -- so imagine swapping the delights of broken glass and chrome for grass, trees, parrots and large Elephants. Okay, maybe not the Elephants. The idea of a dance festival in the middle of an Amazon rainforest DOES sound fantastic, but can you imagine the queues for the taxi?!A four-day dance festival is set to go ahead in the middle of the Amazon rainforest to raise awareness for the plight of the area. The event, to be called EcoSystem 1.0, has been fully supported by Greenpeace and is due to take place from August 2 5. Acts to be confirmed over the coming weeks are Armand Van Helden, A Guy Called Gerald, Grooverider and Moby.
