Chart-topping titan Coldplay will start the next leg of its North American tour earlier than expected with a 24-city spring jaunt. The trek kicks off May 15 at Cruzan Amphitheatre in West Palm Beach, FL, and wraps temporarily on June 20 at General Motors Place in Vancouver, BC.

Highlights for the spring outing include a May 17 gig at Lakewood Amphitheatre in Atlanta, GA, a May 26 event at Susquehanna Bank Center in Camden, NJ, a June 6 concert at Sommet Center in Nashville, TN, and a June 15 show at MTS Centre in Winnipeg, MB, among other dates. Ticket sales for select dates begin over the next two weekends.

Coldplay previously announced a brief summer 2009 tour leg that will hit more than 10 markets across the U.S. and Canada. That leg of the outing picks up July 10 at the Amphitheater at Clark County in Ridgefield, WA, and closes August 9 at Ford Amphitheatre in Tampa, FL.

In between the spring and summer North American jaunts, the band is scheduled to perform a few European music festivals, followed by a larger European venture running through late summer. Coldplay is currently on a month-long trek of the Asia-Pacific region, with upcoming stops in Australia, New Zealand, Singapore and China.

The Grammy Award-winning band is continuing to tour behind its fourth studio album "Viva La Vida or Death and All His Friends," released in June 2008. The chart-topping record earned the title of Best Rock Album during the February 8 Grammy Awards ceremony, while the hit single "Viva La Vida" raked in honors for Song of the Year and Best Pop Performance by a Duo or Group.

In addition to all its jet-setting, Coldplay has also been spending some time in the studio, though drummer Will Champion noted that a follow-up to "Viva La Vida" isn't in the immediate future.

"It's a very strange time for the way people listen to music. It's getting more and more fragmented, with people buying single songs rather than albums," he noted in an interview on the band's Web site. "In many ways, it's going back to the way it was originally, where people would release singles and then an album was a collection of singles."

Champion added, "We want to do something totally revolutionary, that hasn't been done before. We're writing with a view towards that. But what that is, we don't yet know."
