So you don't care about prog metal? How Metallica's concept albums with time signature changes and lengthy multi-section songs pioneered (in metal) many of the things DT are known and praised for?
Nope, don't care.
Aside from DT, I really don't care for much prog metal anyway.
And any way, it's the prog and melodic metal influenced stuff I like best. Stuff like Train of Thought or the heavier songs on the more recent albums are OK, but they don't do a whole lot for me.
BTW, you can say all you want about DT owing a ton to Metallica, and you wouldn't be completely wrong, but really, they are outside the bands that DT have claimed as the largest influences. Awhile back, either Mike or John said in an interview that there were only three bands that DT were still willing to open for, now that they were a band that could support themselves with their own fanbase. Those bands were Rush, Iron Maiden, and (I believe) Yes. Those three bands and their styles are really the biggest to the DT formula. That formula BTW was already in the works when Metallica were writing MoP and AJFA, so I don't see how DT owe them that much really. Initially, influences such as the bands I already mentioned and more pioneering prog metal acts like Fates Warning and Queensryche were far more important to DT than Metallica were.
Honestly, the idea that Metallica pioneered prog metal is kinda ridiculous, the more I think about it. Metallica were the ones *influenced* somewhat by prog metal, not the other way around, and to give them some sort of credit for pioneering it is really bizarre and incorrect.
