Forget hard rock, heavy metal and hip-hop: Electronic music is the new scene for hard-core concerts.

CNN reported that between 30 and 80 concert attendees were hospitalized after a show by Swedish electronic dance artist Avicii on Wednesday at the TD Garden in Boston.

Massachusetts General Hospital informed CNN that 13 of the patients are between ages 16 and 19. Most of the complications were due to dehydration, drugs and alcohol.

"Fortunately, no one was seriously injured. Mostly underaged kids involved in alcohol and/or some illicit drugs," Boston EMS Deputy Superintendent Mike Bosse said, as quoted by the Boston Herald. He claimed many of the concertgoers were drunk when they got to the show.

"This is a mass casualty incident that greatly impacts our resources -- Boston police resources, as well as area hospitals," Bosse said. Several ambulances and service vehicles were on the scene, and a bus was called to transport 10 teens to the hospital.

"There was one kid, it took four cops to take him down," one attendee told CNN. "He was on something. I have no idea."

Incidents such as this have become common at techno and EDM concerts. At the Electric Daisy Festival in Las Vegas last weekend, two people died and nearly 800 were treated for medical conditions. Avicii was one of the performers at the three-night event, which attracted over 400,000 fans.

Avicii (real name Tim Bergling) is a two-time Grammy-nominated disc jockey, remixer and producer. His hits include "Wake Me Up," "Levels" and "Hey Brother." He was No. 3 on DJ Magazine's list of Top 100 DJs two years in a row.
