The three groups are just the first glimpse of what promises to be a star-studded lineup at Millennium Stadium in Cardiff, Wales.

Organizers say the aim of the One Earth Concert is “to engage the public in positive action to tackle climate change, and to encourage 1 million Europeans to switch to renewable energy sources by September 2006.”

The concert is being presented by climatechangenow.com.

Tickets are already on sale through Ticketmaster.
