Aerosmith guitarist Joe Perry is in stable condition after he was taken to a hospital during a performance in New York.
Perry, 65, became ill around 9:30 p.m. Sunday while performing with Johnny Depp and Alice Cooper in his side band, the Hollywood Vampires, at Ford Amphitheater in Brooklyn's Coney Island.
Sources told The New York Post Perry lost consciousness on the scene and police revived him.
A concertgoer told FOX411, “[Joe Perry] was sitting by the amp on stage during the first song. I thought that was odd. He walked behind the stage. The show kept going. They didn’t stop.”
Hollywood Vampires record label rep Sujata Murthy says Perry is "stable and resting." Cooper also tweeted "our brother" Perry is stable and with family.
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.— Joe Perry (@JoePerry) July 11, 2016
A message was also posted on Perry's account thanking fans.
A video posted by a fan on social media shows Perry sitting down on stage and then walking off in the middle of a song and stumbling.
The band continued playing after Perry left the stage.
