Five, seven, five. These are the incremental dimensions known as the haiku. In written and spoken language, these numbers translate into syllables, forming a collective literature of single-serving reflection. When those numbers are stretched to represent minutes rather than syllables, their relative size diminishes in terms of its self-evidence, but in the hands of the musician named Mystified, the matter of reflection remains. The netlabel Subterranean Tide has released a three-track collection by Mystified, each track taking its length and title from a line of haiku, in this case a work whose central subject is sound: “Night cicada; / having slipped upon some dew / to the moon he cries.” The first track is five minutes long, the second seven, the third five again. Each is a mix of what might, in other contexts, be thought of as ambient industrial music, except that the notion of the cicada transforms the background hiss into the imagined constant whir of insectoid activity (at times what appears to be an actual cicada is also heard). There is a variety of droning, lightly percussive sonic material, and the highlight may be around two thirds of the way through the second track, when the combined rhythmic elements form something that might even be considered a groove.
