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.
