Trepaneringsritualen is an industrial and dark ambient project created in 2008 by Swedish artist Thomas Martin Ekelund.
Pitchfork defined the project as "heavy ritual ambient" with "an almost psychedelic quality". Orlando Weekly described it as "an immersive experience with few equals in the world of experimental music, a pagan assault on all the senses".
The name Trepaneringsritualen is a reference to the surgical intervention in which a hole is drilled or scraped into the human skull known as trepanning.
Trepaneringsritualen explores themes of religion, magick and the occult realms of consciousness, taking its musical cues from the old school of ritual ambient & death industrial. Rhythmic and seething at times, and oozing forward with a creeping sense of desolation, Trepaneringsritualen conjures forth bleak but mesmerizing visions of the end-times.
He releases on labels like Cold Spring, Pesanta Urfolk, Malignant, Silken Tofu, Hanson, iDEAL, Release The Bats and Black Horizons to name but a few.
T × R × P have performed countless live rituals across the world, including festival such as Stella Natura, Wave Gothic Treffen and opening slots for a broad spectrum of artists including Old Man Gloom, Circle, Bölzer and many more.
