Aru Machi no Gunjō

"Aru Machi no Gunjō" (或る街の群青, A Town In Blue) is a song by Japanese rock band Asian Kung-Fu Generation. It was released as the lead single of their fifth studio album, World World World, on November 29, 2006. The song was conceived on tour when the director of the then-upcoming anime film, Tekkonkinkreet, approached the band and requested a theme song for his film. AKFG proceeded to compose the track and released it as a single a month prior to the film's December 23 debut. The single peaked at number four on the Oricon charts and sold over 50,000 copies in 2006 alone, becoming the 199th single of the year. The song was ranked 5th on fans request for band's 10th anniversary live setlist on September 14, 2013.
