Catalyst, a brilliant piece of sophistry there but astoundingly true. I think there is nothing special or unique about Perth metal as such (it is influenced by the international scene) but that it is a just as anywhere else made up the fans who find whatever solace they can in the music and by but large it is the music itself, the musicianship, the riffs, pounding drums and range of vocal stylings...as you say its not the need to the need to be rebellious which drives the metal machine...
