東京事変
Tokyo Jihen started as Ringo Sheena's backing band at first for her last concert tour before ending the first half of her solo career. Sheena was contemplating working with a band while working on her last solo album, "Kalk Samen" "Kuri no Hana". She began looking for members of her backing band to support her solo tour "Sugoroku Ecstasy" in the Autumn of 2003. The tour band was introduced as Tokyo Jihen during the tour for the first time, featuring guitarist Mikio Hirama, pianist H Zett M, drummer Toshiki Hata, and familiar bassist Seiji Kameda. The musicians she selected became the core of what would become Tokyo Jihen.
