A Friday night concert by The Chainsmokers in San Jose, California, prompted a significant emergency response after more than a dozen attendees needed hospital care.
ABC7 reported that fourteen people were transported to local hospitals during and after the electronic music duo’s outdoor show at Discovery Meadow on Friday, September 4, according to the San Jose Fire Department and local police. Authorities said the medical calls involved a range of concerns.
Police told NBC Bay Area that some cases involved “suspected alcohol intoxication and drug-related issues.” Officials have not released the identities or conditions of the hospitalized people.

The SJFD said on X that it “immediately requested an Ambulance Task Force, two additional advanced life support fire units, and a Battalion Chief to manage the incident and provide additional medical resources.”
Fourteen ambulances ultimately responded to Discovery Meadow.
Video published by ABC 7 showed a line of ambulances outside the venue along with a fire truck as crews worked at the scene. The emergency response lasted roughly two hours. The fire department said all of its resources had returned to service by approximately 10:34 p.m.
