Let’s Dance! At iHeartRadio Music Festival featuring Lady Gaga, Jennifer Lopez, Black Eyed Peas, Bruno Mars and more!

They’re calling it “the biggest live music event in radio history”, and judging by the list of performers, this event may do justice to the hype. Announced today by our beloved Jennifer Lopez, the iHeartRadio Music Festival takes some of the hottest acts in music to Sin City’s MGM Grand for two nights of celebration in honor of the launch of the new online radio social hub.

The Friday, September 23 show features Coldplay, Alicia Keys, The Black Eyed Peas, John Mayer, Carrie Underwood, Bruno Mars and Jane’s Addiction.

The Saturday, September 24 date includes Lady Gaga, Jennifer Lopez, Steven Tyler, Kenny Chesney, Nicki Minaj, Rascal Flats, David Guetta, Sublime with Rome, and the special guest performance by Usher and Sting. More acts will be announced throughout summer.

American Idol host, Ryan Seacrest, will host the two-night music festival. On Seacrest’s online site, the event is being compared to Woodstock but with “more glitz and less tie-dye”.
