9:20 AM PT -- Law enforcement sources tell TMZ one of the pyrotechnics fell over when the firework unit malfunctioned, causing a spark to shoot out.
Two people in the crowd suffered minor injuries -- one person hit in the stomach and the other in the eye. They were both treated on scene.
ODESZA's set at Life is Beautiful Music Festival came to a terrifying end when a rogue firework shot off straight into the crowd.
The group was finishing its set Sunday night at the Las Vegas event with a massive firework display when something clearly went wrong, and one of the explosions went off in the crowd. It's unclear how many people were injured from the blast.

One member of the audience wrote of the mishap, "Literally saw someone get hit by an explosive firework RIGHT next to us during the ODESZA set and it was SOO traumatic. Wtf."
ODESZA was among one of the last acts of the weekend for the annual music festival. Other performers included The Weeknd, Travis Scott, Arcade Fire and Florence + The Machine.
