Greek opera's electronic riot symphony

Anarchists are calling for demonstrations in the central Greek town of Amfissa.

The demonstrations are planned to coincide with the trial of the policemen, accused of murdering a 15 year old schoolboy, in December 2008, which sparked the country's worst riots in decades.

A group of classical musicians from the Athens opera, and another orchestra, have composed a 70 minute electronic symphony in praise of the young people who took to the streets.
