Aerosmith vocalist Steven Tyler recently voiced his strong opinions of KISS during a radio interview.

"KISS is a comic-book rock band," Tyler said. "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," he continued. "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 I, sometimes — depending on the time of day — 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 ourselves seriously. And I feel like you do. We would come on stage [after KISS] and I would think it was a little 'comic book.'"
