Sakanaction is getting ready to release their concept album "Natsukashii Tsuki wa Atarashii Tsuki ~Coupling & Remix works~" on August 5. They have unveiled the PV for one of the tracks off of the album called "years". 

"years" was the coupling track to the band's single "Bach no Senritsu o Yoru ni Kiita Sei Desu." which was released back in July of 2011. Yamaguchi Ichiro (Vo, G) wrote the song shortly after the Tohoku Earthquake to depict the worries that people have. 

Four years after the song was released, the PV has finally been created. It was directed by Yamada Tomokazu with the theme "feelings of the city".
