"The iHeartRadio Music Festival is the ultimate celebration of what's hot in all genres of music, from rock, pop and country to electronic dance music, R&B and hip hop," said Tom Poleman, Executive Producer of the festival. "For the first time, fans from across the country will get to see today's megastars like Rihanna, Taylor Swift and Usher on the same stage as legends like Aerosmith, Mary J. Blige and Bon Jovi. I'm sure we'll have hundreds of memorable moments throughout the festival. It's the concert line-up of the year for both fans and artists."
