Not content with being named as Billboard’s ‘Group of Decade’ and kicking off 2010 by performing at the Closing Ceremony of the 2010 Winter Olympics, NICKELBACK show NO signs of slowing down, as they have extended their Dark Horse World Tour with another mammoth run through the USA. For our American readers, the full list of dates and the ticket buy links can be found HERE.

Since it kicked off around the release of the album back in November 2008, “Dark Horse World Tour” has been a smashing success, as all previous legs have been completely sold out. Since 2009, Nickelback have sold more than 1.6 million tickets and have played more than 120 global shows.

“Our fans have been amazing all over the world from Japan to New Zealand, Australia, Dubai, the UK and North America,” said Nickelback’s Chad Kroeger. “Our fans keep us going and we are excited to play 25 more dates in the US with Three Days Grace and Buckcherry.”

In other Nickelback news, the band has just released select songs which will now be available as downloadable content for Xbox 360, PlayStation 3 and Wii platforms in the Rock Band Music Store.
