from what little i could find, they started punk/hardcore and crossed over to metal. I don't really see it, but i've only managed to hear WHERE LEGENDS BEGAN. What I'm hearing is constantly evolving riffs, but not in the annoying tech way. They're structured with the vocal melodies and almost tell a musical story!! the guitar sound itself is magnetic and wonderful! it just fits so nicely! like on the previously mentioned albums, rust in peace, or ride the lightning.
what comes close to being the only drawback are the vocals/vocal melodies. which i know are oh so important! they're very similar to blind guardian's first two albums, which i can handle just fine! actually, i think my only drawback is that i can't crank it because of the shared home. i want it louder!
