Tapio Kotkavuori is a Magister of the Temple of Set and he has an essential role in the practises and information sharing of northern magical context. He is also the author of two books on the subject of Left Hand Path. Terra Hyperborea contains a selection of Kotkavuori's sound-magical Workings recorded in 2001CE. At the time, recordings were made under the project name Vaskikäärme. These recordings have now been remastered and are publicly available in CD-format for the first time. The album contains also a high-resolution version of the Underground Tunnels-video. Musically artist himself describes Terra Hyperborea as "post-apocalyptic dark-ethno-ambient". Its semi-organic, semi-electric soundspheres are trance inducing, almost hypnotic, varying from soft mood adjustments to more focused incantations and chants. Kotkavuori's main weapon of choice in this battle against silence is didgeridoo, but tons of other instruments - such as vocals, rainstick, shaman drum, coffee maker, synthesizer, kitchen knives etc. - have been utilized as well. All in all, these recordings create a shamanistic ambiance with a dark twist characteristic to the Left Hand Path. They provide an inspiring background for mundane as well as Other Kind of activities. To some, this record offers an unique peek to the world of Black Magic. To others, it offers a lot more.
