Wander,
Are you openly admitting to disrespecting Power Quest on their own forum? That's REALLY lame and immature, IMHO.
Back on topic...
Symphony X are one of those bands that when I first got into them, found to be amazing. I guess because they are different than most power metal bands. For some reason, they have not stood the test of time for me too well. My interest in them these days is fairly minimal.
I have seen them live a couple times, and they have always been great, so I would certainly recommend going to see them for those interested.
