MAXIMUM THE HORMONE

Maximum the Hormone is a Japanese heavy metal/hardcore punk band from Hachiōji, Tokyo. Their lineup has consisted of vocalist Daisuke-han, drummer Nao, guitarist Maximum the Ryo-kun, and bassist Ue-chang since 1999. Each member alternates singing lead vocals, often within the same song, with the exception of Ue-chang, who provides backup vocals almost exclusively.
The group is best known for their unconventional and experimental style of alternative metal music. Over their career, they have found success incorporating elements of heavy metal, hardcore punk, hip hop, pop, funk, and ska into their sound. Stylistically, their music runs the gamut from being dark and serious, to ironic or humorous, often with drastic shifts in tempo and mood over the course of a song. The band's eclectic nature frequently draws comparisons to System of a Down.
