Aerosmith's Joe Perry On Steven Tyler : "He's Got To Get His Act Together"

Joe Perry is angry that Aerosmith has been sidelined due to Steven Tyler's tour injury.

The group had to cancel their summer tour after the frontman suffered injuries when he fell off the stage during a concert in August.

"The tour was building up to be a great tour, and I was pretty (upset), you know," Perry said in an interview.

The guitarist hasn't even spoken to Tyler recently: "I haven't talked to him in over five weeks. I don't know what's going on with him. I hear he's getting better, but I don't know I really don't know what's going on with him."

The 61-year-old Tyler fell off the stage during an Aug. 5 performance in South Dakota. He broke his left shoulder and needed 20 stitches in his head. Tyler was ordered by doctors to take the time to properly recuperate from his injuries.

"I was pretty (upset), because right before that, he had pulled a muscle in his leg. And we had to take two weeks off and we missed probably seven dates," Perry said.

Even though Aerosmith is idle, Perry has been keeping busy promoting his upcoming album, "Have Guitar, Will Travel." It's the fifth record for his solo endeavor, The Joe Perry Project. Although the CD was already in the works, he put his full focus on it after Tyler was injured. It is out Oct. 6.

"The bottom line is that every hole that Aerosmith left I filled," he said of the CD.

Aerosmith has been together since the early 1970s, and Perry believes they'll be back in action again: "One thing I do know, there's still life left in the old band."

Still, Perry couldn't hide his feelings regarding Tyler.

"All I know is he's got to get his act together. I mean, he and I haven't written a song together alone in the same room in over ten years, so there's been some changes in (the) paradigm of what Aerosmith is," he said.
