For several years, Hiroshi Hasegawa made horrific noise as a member of the quartet C.C.C.C.. Since 1993 he has also recorded horrific noise on his own under the name Astro, and Echo from the Purple Dawn finds him continuing his exploration of analog sound mutation using oscillators, ring modulators, and field recordings. The three tracks on this album (titled simply "Echo from the Purple Dawn 1, 2 and 3") are all incredibly dense and crunchy tapestries of non-melodic noise, varying slightly from each other in color and texture but generally offering impenetrable walls of abrasive and high-volume chaos. The first track is actually the least interesting of the three, a construction of densely glistening growls and howls that morphs slightly over time and at varying speeds. On the next track, the noises sound more random somehow; no clear structural pattern emerges to unify the shimmering layers of glitch and the occasional subhuman yowls. The third (and longest at 32 minutes) is the most interesting, and also the most disturbing: it offers lots more textural variety and a much more carefully defined mood. That mood is dark and foreboding, with occasional incursions of science fiction spaceship sounds, moments of industrial skronk, and an overarching sense of apocalyptic monstrosity. Fun? No. Fascinating? Sporadically, yes.
