400BadRE:Quest-Rock band Japan-

400BadRequest
Formed in 2025, this Japanese rock band is centered around vocalist 4B and guitarist MA396.
With the tagline “Delivering intense pain through deeply depressive introvert rock,” their music is defined by lyrics filled with hopeless despair and profound sorrow, paired with emotionally explosive sound.
Their songs span heavy rock, loud rock, and beyond, occasionally incorporating progressive elements.
A dynamic contrast of stillness and intensity, chaos and precision, vividly expressing inner darkness.
Let the pain resonate.
