In a new interview, Aerosmith guitarist Joe Perry revealed he has recorded a secret project with Paul McCartney, Alice Cooper, and actor Johnny Depp.

"It's a project that we're keeping under wraps for now," Perry said. "There will be [an announcement when the time is right]."

Perry said all the musicians recorded the music together multiple times until they were satisfied with the recording, as opposed to each musician recording their parts individually.

"I was in the studio with Alice Cooper and Johnny Depp, playing guitar, and the three of us are looking at each other like, 'Hey, we're sitting here with Paul McCartney!'" Perry said. "And we're all looking at each other like open-mouthed kids. Paul was really nice. He's all about business [when recording]. At 72, he can still hit all those notes."
