Updated: Join Coldplay on Tour!

Calling all unsigned bands, Coldplay is launching a contest online to find the next great band. The winner will get to tour with Coldplay as the opening act for their Viva La Vida tour this summer.

Contestants are urged to make YouTube videos and submit them via internet on their YouTube channel at youtube.com/coldplayingTV.

The video cannot exceed 5 minutes in length. There will be one winner each in Boston, Chicago, Washington, D.C., Hartford, Philadelphia, and San Jose, California. The grand prize includes an opportunity to play for up to 20 minutes as the opening act for the band, $2,000, and ten tickets to the Coldplay's concert for their friends.

The contest will run until July 7 at the latest, depending on the city. Good luck!
