iHeartRadio recently announced their highly anticipated fall festival lineup, which includes big name acts such as Muse, fun., and even Queen. The festival is a two-day event on September 20th and 21st.

Held in the colossal MGM Grand Garden Arena in Las Vegas, iHeartRadio’s music festival is a gathering of top artists of multiple genres, from pop to indie to classic rock, and will be an event to remember. Taking the place as frontman for Queen is American Idol star Adam Lambert, who controversially walked away from his label, RCA Records, due to his refusal to do an all-covers album. Other acts include 30 Seconds To Mars, Ke$ha, and Keith Urban, just to name a few. The festival is also utilizing its radio roots to provide “listen to win” contests. From the festival website:

You and a guest will fly round-trip to Las Vegas for a 2-night, 3-day stay and you’ll have access to tons of amazing music with tickets to the iHeartRadio Music Festival Village during the day, and tickets to both nights of the iHeartRadio Music Festival at the MGM Grand Garden Arena.
