Part pop concert, part controlled chaos, orchestrated by a rigorous director – this is Japanese subculture conveyed in all its multi-coloured, cacophonous, frenetic glory. You’ll be equipped with rain poncho and ear guards but you’ll still be surprised by what is thrown at you, as twenty-five actors storm the stage. Confronting you at breakneck speed, they bombard the senses with a precisely choreographed medley of dance, music, bellowed slogans and video clips. Founded by Tokyo-based artist Toco Nikaido, Miss Revolutionary Idol Berserker pays homage to otagei – geeky dance routines performed by superfans to their Japanese pop idols. Kitted out in rainbow-hued costumes and armed with an abundance of disposable props, her riotous company breaks down the barriers between cast and audience as it hurtles towards a festival-like finale that invites everyone to take part.
