Video: Heavy metal with a political message from Ai Weiwei With it he has released a music video showing two emotionless prison guards who watch Ai as he eats, sleeps, paces, showers, and even sits on the toilet, much of it metaphor designed to mock state power. Ai has used his art to draw attention to injustices in China and the need for rule of law. His video depicts an insensitive, overbearing state power that ignores individual rights. The explicit Mandarin lyrics of "Dumbass" are sung by Ai himself, who said he has found in music a therapeutic way to break through the memories of his ordeal. The music was composed by Zuoxiao Zuzhou, a Beijing-based heavy-metal artist and friend of Ai who has also experienced several run-ins with the government. For the video, shot in a studio in Beijing, Ai brought on board renowned Australian cinematographer Christopher Doyle, who has shot films for Hong Kong director Wong Kar-wai, among other renowned filmmakers
