The Dixie Chicks are doubling their State Fair fun this summer by adding a second grandstand show at the Great Minnesota Get-Together.

The Grammy-winning country trio is tacking on an Aug. 28 show to the previously announced performance a day earlier as part of a world tour.

Tickets for the second State Fair concert, priced at $57 and $67, will be available at 10 a.m. on Dec. 11 Friday through Etix at etix.com or by calling 1-800-514-3849. They can also be purchased at the State Fairgrounds from 10 a.m. to noon. For details, call 651-288-4427. The first show sold out.

One other grandstand date that has been filled so far: Demi Lovato and Nick Jonas on Aug. 31. More acts will be announced in the coming weeks and months for the fair, which runs from Aug. 25 through Labor Day, Sept. 5.
