Early demo CD-R. The band's first vocalist had seceded around November, so it's unclear if he's featured.

The exact tracklist is unclear; sources list the first track as Atama Furi Kyoku (頭振曲), but that's likely a descriptor rather than a title (“head swinging song”). The second track would go on to be remade a number of times.

This single's name was later reused when the band released their first official maxi-single.
