The lineup for the 2017 iHeartRadio Music Festival has been announced, and two big country names are on the bill for this year. Among the artists scheduled to take the stage at the festival, set for Sept. 22 and 23 at the T-Mobile Arena in Las Vegas, Nev., are Chris Stapleton and Thomas Rhett.

Stapleton will be performing on Sept. 22, while Rhett is one of the closing acts of the festival on the following day. Other performers at the 2017 iHeartRadio Music Festival include Coldplay, David Guetta, Lorde and Kesha. Ryan Seacrest will be hosting the event.

The 2017 iHeartRadio Music Festival will feature two stages: one for the top-billing acts such as Stapleton and Rhett, and another in the Daytime Village area. On that stage, open on Saturday, country fans will find Kelsea Ballerini; also scheduled to perform there are All Time Low, French Montana, Noah Cyrus and Niall Horan, formerly of One Direction.

Stapleton’s most recent album is From A Room, Volume 1. The singer-songwriter released the project on May 5; his most recent single is the record’s “Broken Halos.” From A Room, Volume 2 is due out later this year, though no official release details have been announced.

Rhett is currently working on the follow-up project to 2015’s Tangled Up, and he's currently out on the road, on his Home Team Tour. Rhett and his wife Lauren recently brought home their adopted daughter, Willa Gray, and are awaiting the arrival of their first biological child, also a girl; Lauren is due in August.

Tickets for the 2017 iHeartRadio Music Festival will go on sale on July 28 at 1PM ET. More information about the two-day event can be found on the festival's official website.
