Cool? I hope you're joking. These guys can play like nobody's business (though their songwriting model is a good bit too repetitious from what I've heard), but the cheese factor is through the roof. I have kind of a love/hate thing with them, but I wouldn't in a million years say they're cool. They're pretty much the antithesis of cool. They're everything that's horrible and cheesy about power metal, but they play awesome and can really do some good shit when they put their minds to it.
So yeah... I just don't know. I haven't actually bought an album yet, and I don't know that I ever will, but they're certainly interesting.
