On-Gaku: Our Sound

Three high school delinquents form their own rock music band despite having no musical experience. They steal instruments from school and play harsh, rhythmic noise, inspired by a musician who thwarts a robbery. Their band name, Kobujutsu, is initially meant to intimidate but ends up being used by an opposing gang, leading the trio to seek out other opportunities, including a rock festival where they reunite with another band led by Morita.
