Awesome as metal band from Mildura in Australia. With influences from Megadeth, Delian League, Dream Theater, Metallica, Pantera, Iron Maiden, Metal Church, Iced Earth, Mudvayne and Slipknot. with their own unique metal sound these guys rock hard, hence the fact that "DEFCON are better than your favourite band!" - Keep A'rockin you guys.
me: hey dude, you see DEFCON last week?
guy: HELL YEAH! they kicked ass, best band of the day!
me: totally. lets go see them next time they play?
guy: sure! they rock!
