Spiracle" has flown to the stratosphere in "Ananta" and has swallowed the milky way in "Lumen". Now it opens the gate to the parallel worlds through the astral body.
Side A: Evestrum is formed by membranous layers of drones, which slowly shift by the interference between glass harps and moderate electronic sounds.
It is a sonographical report of the process: a subtle spiritual existence merges into a physical body and becomes tangible through the senses.
Side B: Exusiai is formed by the resonance of trumpets and metal sheets that were recorded in a dark vast basement.
It is a collected mass of sonic phenomena: a warm invisible energy like sunlight timelessly infiltrates into infinite darkness like ripples.
The original materials of "Evestrum" were recorded by a 4-track cassette recorder in Kagoshima in Japan in the late 90's. Other recordings in the same period were used in "Flood", which was included in "Sympathetic Field" released in 2002.
The original materials of "Exusiai" were recorded in 2004 in Switzerland. Some other recordings in the same day were used in "The Epidemic Symphony No.9" released in 2006.
However the compositions are rather close to "Lumen" released in 2007, in the meaning that one material is treated as a core of the structure, and focused on the physicality and the osmosis of the sound.
The cover art is paradoxically representing invisible world - an object which is filled with invisible matters.
This title is the last release of Hitoshi Kojo as Spiracle.
