Harmonix just announced their plans to release Rock Band: Country Track Pack on July 21, 2009. The Country Pack will be coming out for the Xbox 360, PlayStation 3, Playstation 2, and the Nintendo Wii. Rockers will get 21 new country songs to play with from musicians like Kenney Chesney, Shania Twain, Alan Jackson, Kenny Rogers, and Rascal Flatts.

At least some of these new songs will remain exclusive to the Country Track Pack for at least a little while before becoming available on the Rock Band Music Store. There may be additional songs and artists as well; Harmonix stated that more details will be announced in the next couple of months before release.
