While backpacking around Europe, travelling in one of its nicest forests you stop to relax and listen. Birds, insect and many other creatures make strangely mesmerizing noises. Suddenly you hear something that is not supposed to be there. You hear the sounds of drums.
Curious, your friends and you decide to go have a look and as you approach the strange sounds you end up standing in front of what seems to be an old shed. The sounds are coming from in there, you are certain of it.
