65-year-old Perry was performing with the 'Hollywood Vampires' at the Ford Amphitheater at Coney Island Boardwalk. The band consists of Perry, rock legend Alice Cooper and movie star Johnny Depp.
Concertgoers say Perry collapsed about thirty seconds into the performance. Perry was playing guitar while sitting next to the drummer, and then begins to get up and walk off stage. Fans say he looked 'noticeably ill'. When he walked backstage, concertgoers said he fell.
Firefighters then rushed on the stage to help carry Perry off. A member of the audience, who happened to be an EMT, got on stage and gave Perry CPR.
The NYPD confirms to ABC News that Joe Perry was listed in stable condition at Coney Island Hospital, and was later transferred to Columbia Presbyterian Hospital for an unspecified reason.
