Aerosmith singer Steven Tyler was asked about the band's tour with KISS in 2003 and he wasn't all positive about it.
He said: "It was like you were watching a different level of concert. KISS is a comic-book rock band. They've got a couple of hits, but they're more, they're comic book, you see them in their spackled faces."
"We were always a band that had something to prove. We always wanted to blow off whatever band it was. And I remember when we went out with KISS in '76 or something, one of our roadies got into a knife fight with their guys. And I hated them ever since. But, you know, since then I've gotten to know Gene [Simmons] and Paul [Stanley], and they're beautiful people.
"But it is different. A KISS lick and a Joe Perry lick — two different worlds, and sometimes, I get offended. I hear that and go, 'It's alright. But do they really mean it?' And, 'What's this all about?' And that's why I think Aerosmith has been around forever. We really do take ourseleves seriously. And I feel like you do. We would come on stage after KISS and I would think it was a little 'comic book.'"
