Although ZONE is strongly associated with being a girls’ band, they actually started their careers as a dance group.
This was their major-label debut single, released in February 2001.
The members reportedly felt some internal conflict as they launched into a new style called “bandol,” performing while holding instruments.
Yet this track turned out to be such a bright, hopeful rock tune that you’d never guess at that backstory.
Its positive message—that as long as you have your friends, you’ll be okay—gently gives listeners a reassuring push forward.
