Our 2015 iHeartRadio Music Festival is almost here! Music history will once again be made on September 18th and 19th at the MGM Grand, as our star-studded lineup takes the stage for what is sure to be an incredible weekend full of music. You DO NOT want to miss it! And even if you can’t be in Vegas to see the festival at the MGM Grand Garden Arena, you can still be a part of it.
