Concert producer Live Nation and casino company MGM Resorts International announced Thursday that they’re collaborating on the three-day Route 91 Harvest festival. It is set to take place Oct. 3-5 in an empty lot near the Mandalay Bay resort. Headliners include Jason Aldean, Miranda Lambert and Blake Shelton. Three-day passes for the event start at $169 and go on sale Aug. 1. The event is the latest large festival to launch in or move to Las Vegas in recent years.
