Ai Weiwei is one of China's preeminent contemporary artists, having won numerous worldwide accolades for his architectural feats (such as that awesome Beijing National Stadium from the 2008 Olympics). Problem is, Ai isn't what you'd call a "company man," riling Chinese authorities for years with his brand of political activism that included producing documentaries on political dissidents and subjects considered sensitive by the party. This ultimately resulted in his 81-day detention in 2011 on flimsy tax evasion charges.
So what do you do after being thrown in the clink for nearly three months? You write the most hardcore Chinese metal song since Wing Sings AC/DC, that's what.
