Fleetwood Mac just announced their appearance at this year’s iHeartRadio Music Festival in Las Vegas, marking their debut as a band without guitarist Lindsey Buckingham.

This past April, Buckingham parted ways with the group due to a scheduling conflict about a world tour. So, the band recruited former Tom Petty and the Heartbreakers guitarist Mike Campbell and Crowded House singer Neil Finn to join members Stevie Nicks, Christine McVie, and Mick Fleetwood. Later this year, Fleetwood Mac will perform with its new members on a massive tour, kicking-off October 3 and running through April 2019. This new slot at iHeartRadio will be their first performance together with Campbell and Finn.

“It is an honor to be performing at the iHeartRadio Music Festival for our very first time,” Stevie Nicks said in a statement. “The beauty of an event like this is that it is a true representation of the power of radio. It’s an opportunity for artists across all genres to share one stage and what we all love most — music!”

Fleetwood Mac will join the previously announced artists at the festival including Justin Timberlake, Carrie Underwood, Imagine Dragons, Sam Smith, Lynyrd Skynyrd, Panic! at the Disco, Mariah Carey, Kelly Clarkson, Jason Aldean, Shawn Mendes, Kygo, Rae Sremmurd, and Logic. The two-day event will run from September 21 to 22 at the T-Mobile Arena in Las Vegas and for those who can’t attend, it will broadcast live at radio stations across the country. Live streams will also be available during both nights of the festival at CWTV.com, and a special television program is also scheduled for October 7 and 8.

The event will be hosted by Ryan Seacrest and co-produced by John Sykes and Tom Poleman.
