Japanese ur-punk/rock band formed in December, 1969 by Panta and Toshiaki Ishizuka. The group's name means "Brain Police" (Zuno Keisatsu in Japanese) and was taken from a Frank Zappa song. They rapidly became known for the extreme left-wing opinions expressed in their lyrics. The group released six studio albums before splitting up in 1975. They later reformed in 1991 and again in 2001.
