"... one of the defining bands of Japanese new wave and technopop ..."

I just found Japan Times has some interesting articles about the Drive to 2010s event. One of them also features a photo of Hikashu from 1979.

Notable for Koichi Makigami's distinctive, Kabuki-influenced vocal style, Hikashu were, alongside P-Model and The Plastics, one of the defining bands of Japanese new wave and technopop, although from their poppy debut they quickly tacked in a more experimental direction. At Drive to 2010 they are notable for being one of only a handful of artists to perform at all three "Drive to . . . " events.

I would like to note, at that event, Hikashu is the only band which never cease to exist during those 30 years.

All aboard for Drive to 2010
