You have got to love a project with such a name, right? So why did it take until I heard that Peter Johan Nijland (Distel, Hadewych) cooperated to this release before I actually listened to them? The release is somewhat confusing. There is a tape, apparently released by the band themselves and there are two cd versions, one from a label that was unknown to me (Silken Tofu) and another from Malignant. These are not two versions though, but two parts of the same compilation. Roughly said, the first part (Silken Tofu) contains more industrial sounds, the second more ambient. Industrialwise the project goes from somewhat chaotic industrial, reminding a bit of Objekt/Urian, to darker, but also to more noisy sounds. The second cd is pretty dark with, like I said, more ambient sounds but also with industrial and noise influences.
Trepaneringsritualen may not be brilliant, but they certainly released some interesting material, especially for people who enjoy the good old industrial sound.
