Joe Perry, best known as the longtime guitarist for Aerosmith, collapsed tonight while on stage with his side project Hollywood Vampires. The band, which also include Johnny Depp, Alice Cooper and others, was performing in Coney Island when the guitarist reportedly went into cardiac arrest.

Perry was taken to Coney Island hospital and is now listed in stable condition. Reports from the show say that Perry lost consciousness but was revived after being attended to by members of the FDNY and NYPD.

Alice Cooper also reportedly told the crowd that Perry “was very sick” before the show.
