Enclosure suggests both confinement and protection - sound as shelter, sound as prison. The title carries multiple resonances: the enclosures that contain animals in zoos and farms, the enclosure movement that privatized common lands, the sonic enclosure that surrounds listeners in dense noise. These transitional recordings capture Merzbow poised between decades.

The enclosed quality - density, refusal of empty space - anticipates the wall-of-sound approach characterizing the golden era to come. Akita seems to be testing how much sonic information can fit into a given duration, how completely sound can fill available space. The result feels simultaneously claustrophobic and immersive, threatening and sheltering.
