Yet, another Swizerland's heavy music pioneer of extremity - Samael; established in Sion with the prosthetic intense of highly dark metal influence as their lyrics speaks about human sacrifice, blasphemous lyrics and massive Satanic worshipping.
Their Blood Ritual album should be a good example for studying those mysterious litanies and rituals futher more; Pure Black Metal dark music, growling scream vocalist and excessive use of inverted crosses, mystical hooded figures and plenty of skulls collection images (and) the foursome members - Vorph, Makro, Mas and Xy.
An album which can be consider as one of the heaviest one which came out and made in Switzerland shielding by its terrorizing tracks - Beyond the nothingness, Poison Infiltration, After the Sepulture or Bestial Devotion; heavy enough to sew-shut most of thus filthy mouth of the critics.
"As heavy as fuck - this one is a real chaos ! ..."
