The project by Mutsumi Yanagiya of the band BATTLE OF NINJAMANZ that rooted psychobilly in Japan—Mutsumi Yanagiya & THE RATBONES. With their sound resonating outlaw folk and level‑kayō music, they have been growing at the speed of light and will return to Billboard Live Yokohama this summer with their new album "OLD BOYS SPECIAL." The 1st stage will feature only a band setup, delivering a mix of old and new songs. Presenting the world of roots music and the joys and sorrows of life in a hard-edged, sometimes humorous manner! The 2nd stage is a crowd-pleasing pop‑kayō revue show featuring dancers and performers! Along with familiar songs, the production at Billboard Live Yokohama will enchant audiences with staging reminiscent of the Showa era's Shinjuku Koma Theater. Furthermore, guest appearances have been confirmed: Kankurō Kudō on the 1st stage and CHIBOW (SKA-9) on the 2nd stage! Don’t miss their unique "my way" world.
