Aerosmith guitarist Joe Perry is resting and "doing well" after sudden illness forced him off a New York City stage and to a hospital for testing late Sunday, a representative for the musician said.
Hollywood Vampires record label rep Sujata Murthy also said Monday that Perry appreciates the public's good wishes.
Perry became ill around 9:30 p.m. while performing with Johnny Depp and Alice Cooper in his side band, the Hollywood Vampires, at Ford Amphitheater in Brooklyn's Coney Island.
An administrator at Coney Island Hospital confirmed the 65-year-old Perry was undergoing tests.
A post to Perry's Twitter account said that he is "under the best care."
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.
The band continued playing after Perry left the stage.
