Kroi is a Japanese band formed in Tokyo in February 2018.
When mixing all colors, you make "black". Kroi replaces "all colors" for "all music genres", and thinks that mixing colors of all music genres will be the trigger of creating some original sounds.
They also like black music, and they try to sublimate influences and shocks received from black music in their own Japanese way. "Black" is "kuroi" (黒い) in Japanese, so they named the band "Kroi"

Members are Leo Uchida on vocals and guitar, Masanori Seki on bass, Yuuki Hasebe on guitar, Daiki Chiba on keyboard, and Hidetomo Masuda on drums. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
