It consists of vocalist Kyo (Dir En Grey), drummer yukihiro (L'Arc-en-Ciel), guitarists Miya (Mucc) and antz (Tokyo Shoegazer), and bassist Hirofumi Takamatsu (The Novembers).
A big fan of yukihiro since his days in Zi:Kill, Dir En Grey vocalist Kyo approached the drummer about working together four or five years previously.
[2] Needing someone more prolific in composing than himself, yukihiro suggested Mucc guitarist Miya, believing he would also match Kyo's style of loud music.
[3] Miya accepted after talking and drinking with Kyo and learning all that the two had in common, such as upbringings and music tastes, including both being big fans of Zi:Kill.
[4][5] It was a while before yukihiro suggested The Novembers bassist Hirofumi Takamatsu and Tokyo Shoegazer guitarist Kiyomi "antz" Watanabe to complete the lineup.
[2] Petit Brabancon was first announced on October 29, 2021, as an unknown act set to perform at the Danger Crue 40th Anniversary Jack in the Box 2021 event at the Nippon Budokan on December 27.
[20] They released the five-track Automata EP on June 14 and held the six-date Indented Bite Mark tour throughout July.
They sold a two-track CD exclusively at the two Tokyo concerts, the content of which depended on the day, and the first Osaka show was a two-man live with Rottengraffty.
[24] Petit Brabancon released their second EP, Seven Garbage Born of Hatred, on August 7 and held the Burst City tour throughout September.
[3] Miya speculated that Kyo wanted to combine his usual intense and loud music with yukihiro's punk-like style of drumming.
[28] Ryōsuke Tarakane of Mikiki wrote that, while based in nu metal, industrial and alternative rock, Petit Brabancon's music is unrestrained by genre boundaries and has an eerie experimental spirit.
[30] When an interviewer for the music website Barks suggested his lyrics express resentment, anger and frustration with the world, Kyo agreed, admitting to having a negative mindset.
