Listen to Swedish House Mafia on iHeartRadio

The beats were booming out of the speakers at the MGM Grand Las Vegas during the iHeartRadio Music Festival when Swedish House Mafia took the stage.

The Swedish trio took to the spaceship-looking DJ booth with a breathtaking audio and visual presentation that consisted of 3 LED rings, multi-colored lasers, midi-triggered visuals, confetti, air cannons, and SNOW (yes, really!).

Steve Angello, Sebastian Ingrosso and Axwell performed an amazing DJ set that featured some of the group's most memorable songs. SHM released the hounds as they began their set with their hit anthem "Greyhound," then saved Las Vegas when they dropped another dance floor destroyer of theirs "Save the World."

The set continued with their brand new, just-released single "Don't You Worry Child." Other hits heard through the speakers of the MGM Grand included "Antidote" and "Miami to Ibiza." 

Usher joined the trio on stage to close out the set with "Euphoria," making it the first time that Swedish House Mafia and Usher performed the song together.

The show at MGM Grand is the first performance in the United States since the guys announced plans to disband in July, making it one of the most anticipated of the night.
