Avicii's show at the TD Garden in Boston, Mass., took a scary turn Wednesday night when at least 36 fans of the Swedish DJ were taken to the hospital.
A "Level 2 Mass Casualty" incident was declared, but there were no fatalities, and better yet, reports indicate all of the injuries were minor to moderate.
EMS workers told the Boston Globe that over 50 people were treated at the scene, and 36 were hospitalized for dehydration, drug, and alcohol issues.
The ages of the victims ranged from 16 to 25.
"You couldn't breathe if you were on the floor," concertgoer Mike Santostefano told the Globe of the show, adding "It was the best and worst time ever."
That about sums up an Avicii concert.
Mike added that he saw several people who "couldn't handle themselves," possibly because "people who don't do drugs come here and do drugs."
Another fan, Roisin Saratonion, said, "You get really hot in there and you just pass out. You couldn't breathe. It was claustrophobic. People get dehydrated."
Following the show, the 24-year-old electronic music producer and performer, a breakout star in the genre this year, tweeted his concerns for fans.
He writes, "Just hearing the awful news abt tonight. Its a terrible thing, I rly hope everyone is ok! My thoughts go to those affected & their families."
