BiS Kaidan was a supergroup consisting of the anti-idols, Brand-new Idol Society (also known as BiS), and the legendary noise
band, Hijokaidan. The group's sound was chaotic and extremely unique, blending the pop-like elements of Brand-new Idol
Society with the harsh noise and feedback of Hijokaidan. The supergroup released its self-titled EP in August of 2013, which
consists of two cover songs, originally done by the Brand-new Idol Society, and five original songs. In 2014, after a few years
together, BiS Kaidan disbanded, shortly before Brand-new Idol Society folded.
