Finnish experimentalists Skepticism are one of the leading
purveyors of the funeral doom subgenre.
The songs contain little standard structure, and consist mostly
of ultra-slow, droning riffs, minimalist percussion (often not
drums in the traditional metal sense), and vocals that are
raspy, growly, and haunting, yet somewhat subdued in their approach.
The predominant instrument, though,
is the keyboards, which often have
that classic evil church organ sound that places the listener
in the perfect frame of mind.
This is not upbeat metal, and it's not headbanging metal, but what
it is is wonderfully done, ambient sorrowful extreme music.
