EXTASY (エクスタシー) forms in Yamanashi (山梨)山梨.
The band record at least one demo with a fourth member - vocalist KOJI - who then seems to secede. At some point, guitarist YŪICHI and bassist UJI change the notation of their names to YUICHI and YUJI, respectively (or is it the other way round?).
At some point around the release of "STALE BLOOD" (around 1998?), the band attempt to recruit a vocalist, a guitarist, a drummer, and a keyboardist - although it is unknown if they are successful or not.
EXTASY was a visual kei band in Yamanashi. They were active around 1999 and are now disbanded.
