专辑简介

The tetractys was a triangle symbol held sacred by the Pythagoreans. It included all the numbers needed to describe the world. It also formed the basis for the Pythagorean musical system but it's also a representation of cosmic harmony. Matti Salo himself describes it as "a mathematical and metaphysical symbol through which all can be seen as coming into being".

Salo has explored this symbol through his compositions and Tetraktys is an abstract concept album, with the story being left open for interpretation by every listener.
