I am standing on a small, circular, walled in square among a bunch of other people. Towards the middle of the square is a small group of men standing in a half moon shape. They wear white shirts, black trousers and red girdles and beside them is a sign proclaiming that they sell CD’S. A few moments pass then they start to sing, a traditional Croatian song sung by a five man choir. The sound is deep and resonant, rising along the circular walls towards the perfectly round hole high above us, reverberating with a force and a clearness of tone that I hardly ever heard before. I stand there transfixed for a moment almost seeing the harmonies bounce off the walls, it is pure delight for the ears.
