The music is great. Maybe the best underground psychedelic rock album from Japan along with People:Buddha Meets Rock (P-Vine PCD-1414) & Magical Power Mako ( マジカル・パワー・マコ) 1st LP & Super Record.
However, do NOT buy this Showbaot SWAX-88 Papersleeve version because the sound quality is very compressed. Instead buy P-Vine PCD-1445 from 1999 or Victor VICL-23056 from 1993 (I have listened to both and they both have much better sound!!!)
