Joe Perry returned to the stage with The Hollywood Vampires at their concert at Rohnert Park in California on Friday (22.07.16).
The 65-year-old guitarist was reunited with his bandmates - including Johnny Depp and Alice Cooper - after he was rushed to hospital after passing out at the Ford Amphitheater at Coney Island in Brooklyn on July 10.
Taking to their official Twitter account, the band - which also includes Matt Sorum from Guns N' Roses and Robert DeLeo from Stone Temple Pilots - announced: "Joe is back! @JoePerry returns to @hollywoodvamps tour tomorrow, 7/22! #JoePerry (sic)"
While it was first thought Perry - who is also in Aerosmith - had suffered a cardiac arrest backstage, it was confirmed that he collapsed due to a combination of dehydration and exhaustion.
Meanwhile, Aerosmith's Steven Tyler expressed his concern for Perry and admitted he felt like the group had been over-booked, leading to the six string strummer's health issues.
He previously shared: "I've had calls in for two days and I'm really concerned. I don't know what's going on with him and his management people. I just don't know and it's starting to scare me a little bit.
"I know they're putting out nothing but, 'He's recovering, he's really good, he fainted, exhaustion.' But I know my brother. And he's just about the only other guy that's just as passionate about his art as I am. He's always asking me to do three, four shows in a row. I know how to maintain my career, my health. I don't think he knows how to.
"I think he's out there and someone's over-booking him. Even though one could say the band booked themselves; well, that's righteous of 'em, but they're doing like eight or nine shows in a row - or five in a row. And I think they're all a little burnt. I think they need to look at that, Y'know, not young anymore, right?"
The Hollywood Vampires will perform their last concert of their tour on Monday (25.07.16) at the California Mid-State Fair in Paso Robles, California.
After that, Perry will have two months to recuperate before he joins Aerosmith on their tour, which kicks off on September 17 at KAABOO Festival in Del Mar, California.
