This anthology is the second compilation from EM Records of the works of the late Henry Kawahara, a media artist and electronic music producer who was particularly active in the Japanese cyber-occult underground of the 1990s, a scene linked with technologies such as 3D (binaural) recordings, brain machines, sound chairs, computer graphics and compact discs. These tracks, produced 1990-95, include a series of recordings described as "Parallel Data Sounds" and "Sound LSD", a "new language system that speaks directly to the cerebrum" using "frequency components that are not perceived by the conscious mind", reflecting Kawahara's interest in concepts such as astrology, love mantras, and astral projection. Also here are two pieces featuring dolphin sounds and human brainwave feedback, as well as pieces from a recording unit called H Music De-perception (HMD) and a group called Xiaoyun. The majority of tracks here were not originally released under Kawahara's name, but this compilation is an essential key to decoding the Henry Kawahara saga
