The minimalistic arrangements of "Ísavetur" consist of whispering voices moaning cryptic evocations or passing by like fading ghosts. You hear klings and klongs of various bells, monotonous drums and several other industrial-like sounds and reverberations. But you have to listen carefully and concentrated. Put on your headphones, close your eyes and enjoy an excellent dark meditation!
If not, these sounds will not touch you more than the unspecific noise of a motorway in the distance.
