Aerosmith will perform on the upcoming season finale of American Idol.

Guitarist Joe Perry confirmed the news to Rolling Stone, just two years after slamming the program, even after he’d already appeared on it himself.

"It's his [Steven Tyler’s] business, but I don't want Aerosmith's name involved with it," Perry famously told the Calgary Herald at the time. "It's a reality show designed to get people to watch that station and sell advertising. It's one step above [Teenage Mutant] Ninja Turtles."

Asked if he’s changed his tune about Idol, Joe explains “It wasn't about the show – it was about how we found out about it {Tyler’s judging gig]. I was pissed off about that whole thing, but I've played on it before and the band is gonna play on it in the last episode of the season to debut the new single. So it's not about the show, it's about how we found out about it. It was a bit of a shock and it took us off balance.”

When they hit the Idol stage, Aerosmith will perform “Legendary Child," which will appear on both the new album – due for release this September – and in the film "G.I. Joe: Retaliation," which hits US theatres on June 29. The group filmed a video for the track with director Casey Patrick Tebo last Friday.

Aerosmith will be on American Idol season finale Wednesday, May 23 at 8/7c on FOX.

As for that long-awaited new album, Perry says “It's really close. We've started to mix. We've mixed a couple of the songs already, but I guess this week we're really kind of rolling into mix mode. We have a couple of tracks left to finish up, just to put some overdubs on, but we're kind of going from the final, final recording tracks to mixing this week.”

The Boston band kick off their summer “Global Warming” Tour June 16 in Minneapolis, MN with special guests Cheap Trick.
