Nickelback, who were named Billboard's 'Group of Decade' and kicked off 2010 by performing at the Closing Ceremony of the 2010 Winter Olympics, are showing absolutely no signs of slowing down, as they have extended their Dark Horse World Tour. The next leg of the tour, produced by Live Nation, will begin on September 14 in Nashville and will run through October 30 in Las Vegas. Three Days Grace and Buckcherry will join Nickelback on these dates. Tickets go on sale to the general public on July 17th at this location.
