In this album, you will delve into the enigmatic realm of subterranean sounds. The acoustics produced by the underground river in the cave I explored last year, 2024, are truly remarkable. There are areas of complete stillness, where, aside from your own breathing, no other sounds are captured by the microphones. The cave system extends for 2,250 meters, with 1,100 meters open to visitors. This cave is a distinctive natural wonder, featuring a lengthy dry gallery that is traversed by an underground river beneath. Locally, the cave is known as Biserna or Zandana and is situated near the quaint town of Shumen in Bulgaria.
