The iHeartRadio Music Awards is taking a groundbreaking approach to the award show format, offering viewers live performances, storytelling and an intimate atmosphere. In addition to performances at the glamorous-tabled show at the Shrine, the event will also feature artists playing the stages of some of Los Angeles’ most iconic venues from The Roxy to the Hotel Café.
