Aerosmith guitarist Joe Perry was forced to leave the stage mid-song while performing with the Hollywood Vampires in New York on Sunday night.

Social media posts from fans who were at the show in Coney Island Amphitheater say that the 65-year-old fell ill while performing alongside Alice Cooper and Johnny Depp, and left the stage.

He reportedly lost consciousness shortly after and was treated by medics backstage.

Perry was taken to Coney Island hospital in critical condition, but is now believed to be stable.

Footage posted on Instagram shows the guitarist sitting down struggling to play then moving behind an amp before going off-stage:

Other musical heavyweights, including Tom Morello from Rage Against the Machine, have published messages of support for the legendary guitarist on Twitter.
