Just to make you happy I went on youtube to check these songs out. AND HOLY SHIT LOOK AT THIS VIDEO:
I WAS LIKE, HOLY SHIT! THE VOCALS ARE BERABLE. Who is that dude singing with them? Hes awesome. But then labrie came in at the 7th octave and ruined the shit. Honestly the deal breaker for me is the vocals with dream theater. Oh yeah and the whole going into a 10 minute long jam in the middle of the song that doesn't add any value to the song, is pretentious, and just showcases each member wanking on each of their respective instruments.
