Last night, longtime Aerosmith guitarist Joe Perry was taken to a local hospital after collapsing onstage during a show in Brooklyn. Perry was performing with Hollywood Vampires, his side-project group with Alice Cooper and Johnny Depp, at Coney Island’s Ford Amphitheater, when he went into cardiac arrest, as Page Six reports.

The band was two songs into its set, playing a cover of Spirit’s “I Got A Line On You” when Perry ambled behind a speaker and collapse. After Perry lost consciousness, police at the venue revived him, carrying him out of the venue. The band finished the show without Perry, and about half an hour after Perry collapsed, Cooper told the crowd, “If you notice one of our brothers is not onstage with us, he was very sick before the show.”

Here’s a fan-made video of Perry’s collapse, though you don’t actually see him falling on camera.

#JoePerry collapsed on stage just now! He had to sit on drum kit and then went behind a small wall and passed out. FDNY and NYPD carried him off quickly. #Aerosmith #hollywoodvampires

Perry is now at a Coney Island hospital in stable condition, and someone posted a tweet on his account to reassure fans that he’s OK:

Thanks to all of the fans reaching out and asking about Joe. He is stable right now, with family and is under the best care.
