Singer-songwriter Ray LaMontagne collapsed during a concert at Nashville's Ryman Auditorium on Sept. 5, and his management later said he was treated by local emergency medical services for heat-related dehydration. He recovered, performed as scheduled in Louisville the following night, and his team said he was doing well, according to wire coverage of the incident.
The detail worth pausing on is where it happened. This was an indoor concert hall in early September, not a stadium in July, and no extreme heat alert was in effect. Several attendees described the room as unusually warm.
