155 meters down in the silver mine in Sala, Sweden, there is a place called "The echo chamber"
Sounds in this place can live it's own life in up to 20 seconds after being released, rolling around between the smooth walls in this egg shaped room. I went there together with, Sandra Lundgren, to hear her sing the old miner song/prayer "Behållt o Gud min fot från fall" (About the dangers and horrors in the underground and protection from the same) Written in the 1700s.
