Zunou Keisatsu, translating to "Brain Police" in English, is a rock band hailed as one of the pioneering groups in Japanese rock music history. Originally formed in 1968 by Panta, this influential group has been characterized by their politically charged and socially conscious lyrics, marking a significant departure from the more traditional and pop-centric sounds of Japan's music scene of the time. Their music blends rock with avant-garde elements and has often been seen as a reflection of Japan's counterculture movement in the late '60s and early '70s.

Throughout their dynamic and intermittently active career, Zunou Keisatsu has maintained a loyal fan base, despite—or perhaps due to—their controversial standing in the mainstream music industry. Their recent releases, such as "乱破" (Ranpa), "暗転" (Anten), and "歓喜の歌" (Kanki no Uta), continue to showcase the band's unyielding commitment to addressing societal themes through their bold and straightforward musical expressions. The albums like "頭脳警察 7" (Zunou Keisatsu 7) and "頭脳警察 3" (Zunou Keisatsu 3) add to their discography, securing their legacy as intellectually stimulating and musically innovative artists in the tapestry of Japanese rock history.
