Maru Sankaku Shikaku (written ◯△▢) was a Japanese rock band credited for being one of Japan's earliest psychedelic groups.
[1] The group formed by Sakuro "Kant" Watanabe in 1970 took their name from the Japanese words for a circle, a triangle, and a square.
Watanabe during this time also worked as the drummer for a band called Murahachibu and published his own magazine.
Eventually several albums of this material were released (in 2001, on Captain Trip Records[1]) but the band broke up later that very same year.
Several years later, members Chiko-Hige and Reck, having played in No Wave bands James Chance and the Contortions and Teenage Jesus and the Jerks, respectively, formed the punk rock band, Friction.
