Muse have been chosen to provide one of the official songs for London 2012.
The stadium-filling group - who were among the stars who have carried the Olympic torch on its lengthy tour of the UK - are unveiling their song Survival.
The track will be played throughout sports sessions at official venues for the games, such as when athletes enter and during the build-up to medal ceremonies.
Frontman Matt Bellamy said: "It's a huge honour to have the track chosen as such a major part of the London 2012 Olympic Games.
"I wrote it with the Games in mind as it expresses a sense of conviction and determination to win."
