Sioux City's Tyson Events Center is on track to set a record for the most sold-out shows in one year.
Tyson Events Center officials say the Lady Antebellum ticket sales are on pace for the sixth sellout of 2011.
Officials say that some good seats still remain for the concert.
The capacity for this concert is near 7,800.
"The great thing about this show in particular is that the floor is all general admission. So, if you want to get a floor ticket, you can get as close to the stage as you want to," said Erika Newton, convention bureau manager.
Previous sellouts this year include Jeff Dunham, Nelly, Sugarland, Elton John and Tim McGraw.
