At first, On-gaku: Our Sound seemed to be a classic coming-of-age story centered around a battle of the bands. The delinquent kids find a new outlet through music, and thus, change as a result of the art. But the indie animated drama proves to be different, because the band Kobujutsu don’t transform into rock stars over a quick montage and a dash of inspiration. They don’t even look the part, with the scribbled art design. Instead, these kids make sounds through two bass guitars, a snare drum, and a tom drum, purely using rhythm to make music. And as these kids dabble with their instruments, On-gaku: Our Sound marvelously unfolds to a funny but sincere slice-of-life tale that celebrates their passion.
