Hiroshi Hashimoto has been recording under the name Contagious Orgasm, or 接触伝染性的絶頂感 (sesshokudensen seiteki zetchoukan), since 1987. Its sound has gone through many changes: from dark and creepy sound constructions to beat oriented music.
These are photos from concerts where Contagious Orgasm played, so they may be of other bands that played the concert as well.
