In what is becoming the de facto encore at EDM shows around the country, 36 people—most of them teenagers—were taken to hospitals last night after an Avicii show in Boston. Believe it or not, drugs and alcohol are thought to be the main cause.

Aside from the 36 fans who required hospitalization, 50 others were treated by Boston EMS at the scene. There were no fatalities and everyone is expected to make a quick recovery (once the drugs wear off). Teens who spoke with the Boston Globe attributed the incidents not just to substances, but also the pit's sweltering environment.

Mike Santostefano, 19, of Millis, said he saw three young women being carried out on stretchers.

"You couldn't breathe if you were on the floor," he said. "It was the best and worst time ever."


Roisin Saratonion, 18, left the concert earlier than planned because "it was just too crazy in there."

Saratonion, of Marblehead, said most concertgoers seemed like they were high school-aged.

"You get really hot in there and you just pass out. You couldn't breathe," she said. "It was claustrophobic. People get dehydrated."

Sounds like a blast.

Last night brought Avicii's 2014 body count to 65: in May, 29 people were taken to the hospital during a show in Toronto.
