LP jacket is translucent plastic with the artwork screened on it and the vinyl is gold colored. Nehan is a Japanese free improvisation & avant-garde rock quintet formed in August 2022. Their performances are initiated by a 9hz brain wave emitted from a testee who has been brought into a deep meditative state via either hypnosis or acupuncture - a very relaxed but very alert state. nehan doesnt begin until the testee has gotten into the state of "nothingness." It is only then that the improvisation can begin.
