CLEAN: Chanel presents autumn-winter 2009-2010 Haute Couture

A group in Hong Kong has formed a complaint choir to turn everyday grievances into music, inspired by a Finnish initiative. The choir aims to foster understanding and community through song, debuting at the city's July 1st Pro Democracy protests. This global movement uses music to positively express complaints, aiming to bring art to the public and push the boundaries of freedom of speech.
