The J-Pop maverick’s greatest hits compilation celebrates her stylistic range and unique sensibility, an intense blend of both menace and kawaii. Stuffed with a half decade of singles—including 2016’s “最&高”—KPP Best glides through high-gloss synth-pop (“PONPONPON”, the appropriately titled “CANDY CANDY”), caramelized prog-punk (“5iVE YEARS MONSTER”), pearlescent psych (“ファッションモンスター”) and more, often in the space of the same song.
