Dark´n sound is the reduction of a sound, or a musical performance on the most necessary: to the sound, the music!
The visitor is in complete darkness; rescued and in a pleasant atmosphere, from the sound surround and can concentrate thus 100% upon the perceived one. External light and the walking along optical phenomena, eye contacts and judgements on the basis of appearance are reduced to zero and allows the perception of depth in the sound. Thus never heard sound varieties can reveal themselves for every visitor and listener gets the feeling to be embraced by the sound.
