About Seiko Oomori
Seiko Oomori is a Japanese singer-songwriter. Her musical career began in the underground music culture of Tokyo's Kōenji neighborhood, briefly playing in the punk band Kuchuu Moranko before going solo and releasing two independent albums until signing with major record label Avex Trax in 2014. Oomori's music style is influenced by idol culture and punk rock among other clashing musical styles, and she is considered one of the early pioneers of the "anti-idol" and alternative idol scenes led by groups like BiS that would eventually give way to the more popular Kawaii metal movement, utilizing shock value and performance art throughout the early parts of her career. Oomori held multiple concerts within Tokyo, including a first appearance at the 2013 Tokyo Idol Festival, a venue she would continue to appear in. In 2018, Oomori created an idol group named ZOC (short for "zone of control") in which she was both a member and a producer. On 9 June 2021, ZOC released their first album PvP, a double-album produced by Oomori herself with additional contributions from Kenta Sakurai, the producer of now-defunct idol group Maison Book Girl.
