It is pure Rock'n Roll. Often classified in the Heavy Metal sections in the music store, but that's what they do nowadays when they hear guitar, the say it's evil. They play rock'n roll and they do it good, just as the great rollers of the sixties. There are a couple of them that would need a pillow during a show, but anyway we don't even notice them. Steven Tyler is like a sexy storm that needs to find its town to destroy and Joe Perry didn't just read the guide "I play guitar course no.1". This is a good orchestra!
