The "Unleashed" greatest hits tour is slated to kick of March 1 at Pittsburgh's Mellon Arena, the record label said.

"We love our band and think the title of the tour 'Unleashed' perfectly describes how we all feel when we get on stage together -- especially in 2009. We're so happy to get back out on the road, perform everyone's favorite songs and see our fans," the band said in a joint statement.

Tickets for the Live Nation-produced tour are to go on sale to the public Dec. 15 at http://www.livenation.com/ and ticketmaster.com.

American Express Cardmembers will have early access to tickets from Monday through Dec. 14th, excluding dates in Uncasville, Ottawa and Montreal.

The first 16 dates of the tour will include stops in New York, Boston, Washington and Montreal, it was confirmed this week by Live Nation, the tour's national promoter.

The tour is slated to continue throughout the spring and summer. Additional dates are to be announced shortly.
