It’s been just over a year since tragedy struck Las Vegas, but the city has bounced back and the strip is once again shimmering. The star-studded iHeartRadio Music Festival brought the house down, but also brought some important messages and a tribute to a city that’s still healing.

Our Heather Mills was backstage and has a look at the big event.

“These men and women up here with me on this stage tonight represent just some of the brave first responders who reacted selflessly on One October,” said one of the hosts on stage.

Before country star Jason Aldean took the stage for his set, he marked the night with a tribute to those lost and those who helped save so many. The concert also commemorated World Peace Day.

Artist Mike Posner said to Heather Mills, “I was lucky enough to write a poem that a bunch of amazing artists, like heroes of mine, helped me read.”

Ryan Seacrest hosts the epic two day even that’s packed with headlining entertainers. He joked, “There’s so many that I can’t remember all them all!”

There are also some unique collaborations from Justin Timberlake and Shawn Mendes to Logic and Ryan Tenner of OneRepublic. Tenner said of the duet, “It was probably one of the easiest records I have ever done with anybody.”

The show includes hall-of-famers Lynyrd Skynyrd. They said, “Us hey, we’ll go out there and give it all of what we got.”

Pop icon Paula Abdul raved, “You get to fan-out! The talent in the building here is pretty amazing.”

iHeartRadio Music Festival is the soundtrack of the best all come to life on stage.
