Pussy Riot

Pussy Riot is a Russian feminist punk-rock collective based in Moscow. Founded in August 2011, it has a variable membership of approximately 11 women ranging in age from about 20 to 33, who wear brightly colored balaclavas and use only nicknames during interviews. They stage unauthorized provocative guerrilla performances in unusual public locations, which are edited into music videos and posted on the Internet. Their lyrical themes include feminism, LGBT rights, opposition to Russian President Vladimir Putin, whom they regard as a dictator, and links between the leadership of the Russian Orthodox Church and Putin.
