Deceh is an anonymous duo featuring the elusive Eleh. Their edition for the Tapeworm series is "a close study of the harmonic composition of a Hammond organ and a Sruti Box with attention given to the organization of isolated frequencies and the effects of these vibrations on brain activity." Like all of Eleh's work, 'Fundamental Structure' is meditative, and, if you like, spiritual, seeming to slow time itself to a malleable blur and opening sublime temporal portals in the process. And while it might be minimal, the purity of the tones and their ultra-subtle oscillations are still deeply engaged with a vividly synaesthetic quality; these are frequencies you inhale with your ears and can almost see vibrating against your skin. It's a beautiful thing and sounds quite lovely on cassette. The program repeats on both sides. Limited edition of 400 copies - Recommended. (boomkat)
