Asheville Police told Fox Carolina that six people were rushed to the hospital, with two of the fans remaining in critical condition as of Sunday morning. Watch Commander Gary Gudac explained to Fox Carolina that “drugs were involved, but officers were still investigating what combination or types of drugs were distributed.” Gudac also said, “the crowd inside the Thomas Wolfe Auditorium became unruly and began throwing bottles and other items at security guards and others in the crowd.”

Update: Fox Carolina now says that “seven people were rushed to the hospital” from last night’s show and that four concertgoers were arrested. Sgt. Dave Romick told Fox Carolina that police “received calls shortly after 10 p.m. that the seven concertgoers had overdosed and were unresponsive at the Thomas Wolfe Auditorium.” Romick added concertgoers “became unruly and began throwing bottles and other items at the officer” as police tried to help.

STS9 issued a statement about Saturday night’s events via Facebook:

Hey all, we’re real sorry about last night in Asheville. We were indeed asked to wrap things up a little bit early due to some folks at the show that needed some extra medical attention. We hope everyone is feeling better today. It’s a good reminder to keep an eye on our friends and family out there and try to help everyone make solid decisions. Our thoughts go out to those that need it most right now.

Here’s the setlist from last night’s show:

Set One: Walk To The Light, Abcees > King Pharoahs Tomb > Exodus (Bob Marley) > King Pharoah’s Tomb > Gobnugget, Rabble, Pianoir, Vapors > Only Light Remains, Click Lang Echo > SUMMIT (first time played)

Set Two: Really Wut > 4 Year Puma > Hubble > Orbital > Hubble, World Go Round, EHM, Kamuy (show stopped)

A fan who was streaming the show captured the early ending around the 58:40 mark as well as the announcement the concert was cut short:

Our thoughts are with those who remain hospitalized.
