Reunion

Released in December 2016, this song is a lavish collaboration.

Produced by Takeshi Kobayashi, it features Motohiro Hata and back number performing together, singing about emotions that sway in the city and the theme of “reunion” that arrives in fleeting moments.

The contrast between Iyori Shimizu’s and Motohiro Hata’s voices is wonderful, evoking warmth within the bittersweetness.

It was used as the CM song for Tokyo Metro’s “Find my Tokyo.” campaign starring Satomi Ishihara, so many listeners will likely recognize it.

In addition, the limited first edition B of the best album “Encore” includes a short film based on this work.

It’s a track you’ll want to listen to quietly when you wish to remember something important amid busy days.

Golden Hour

Despite its glittering title, this track stands out with a hefty rock sound and distorted guitars.

It embodies the band’s resolve to keep stepping onto the stage without settling for the status quo.

The song is included on their seventh album, “Humor,” released in January 2023.

While it doesn’t have a specific tie-in, it was written late in the album’s production and plays a key role in threading a backbone through the whole work.

Shimizu Iyori’s lyrics—confronting the struggles behind flashy success and calmly assessing where they stand now—are sure to strike listeners to the core.

It will powerfully push the backs of working adults fighting day by day and those trying to take on new challenges.

It’s a number with overwhelming intensity that makes you want to experience it live.
