12012
rock band from Japan
12012 (イチニーゼロイチニ, ichi nī zero ichi ni) is a Japanese visual kei rock band. Formed in 2003 in Osaka Prefecture, the group centers its work around the concept of "madness inside a human" (人間の内面における狂気 ningen no naimen ni okeru kyōki). 12012 is also the penal code for the possession of a dangerous weapon in California. The group sometimes performs as "Kyōki Shoji" (凶器所持), which is a translation of that offense.
Musical styles
The band's musical style has changed over the years. Starting out as a hardcore punk band — and later an alternative metal band with some punk elements — after its first two albums Not Obtain+1 and Play Dolls the band's music shifted to a more radio-friendly sound which could be described as a mix of pop and hard rock. After guitarist Suga left, the band slowly drifted back to heavier terrain. The band's current style could be described as heavy metal with alternative and progressive rock influences.
History
In 2007, the band performed the ending theme, "Cyclone", to the Gonzo anime television series Romeo x Juliet, its single being released by Universal Music Japan on June 13, 2007. The group has also toured Japan on many occasions as well as performing at concerts in numerous international locations.
