If you planned to attend the SiriusXM-sponsored Route 91 Harvest in Las Vegas later this year and haven’t purchased tickets, it’s time to make other plans. The three-day event, now in its fourth year, is completely sold out.

This year’s Harvest, held at Las Vegas Village 9/29-10-1, features a star-studded lineup that includes Jason Aldean, Eric Church, Sam Hunt and many others performing in the shadow of the Vegas Strip.

“Three years is not long when it comes to growth of a festival, but this festival had a life of its own from the get-go,” said Brian O’Connell, President of Country Touring at Live Nation. “Las Vegas and country music has always had a special relationship and I think the runaway success of Route 91 Harvest is a product of that, in addition to the artists that continue to come on board and the fans traveling from all over the world to make this festival what it is.”
