I don't know if your statement necessarily holds value in this case. I mean, would you leave those bands off of a "top prog metal list"?
X Japan - This one truly says all that I need to say re: my clueless comment. Seriously? Has he even LISTENED to this band??? If they are prog metal, then I'm a peanut butter sandwich.
Cynic - Great band. Highly influential. Technical? Yes. Prog metal? No.
Mastodon - Prog metal? Really? Again, a highly influential band. No question about it. Forging their own musical path? Without a doubt. Prog metal? No.
King Crimson - Along with Genesis, Yes, etc. one of the pioneering bands of prog rock. Legends. I would even go so far as to say they paved the way for what we call progressive metal. Without prog rock, there could have
been no prog metal. But to classify them as metal is a HUGE stretch...21st Century Schizoid Man notwithstanding.
Rush - Musical giants. Great innovators at every step along the way. In fact, among my musical heroes if you will. However, Rush has not been a metal band for a LONG time now. Don't take my word for it. Read their interviews and they will say the exact same thing. They have long ago left heavy metal behind. In fact, I would argue that their last metal disc was 'Farewell To Kings'. 'Hemispheres' definitely saw the band moving away from metal and in a more prog rock direction. No question about that.
See, here's what I meant by that comment. Most mainstream rock journalists actually hate metal. They scorn it as unsophisticated and hopelessly stuck in the past. A dead genre filled with dead heads. So they really don't listen to it. And they aren't very knowledgeable re: the whole metal sub culture. Therefore, I am never surprised when they get it wrong. Badly wrong. Hopelessly, sadly, albeit unintentionally humorously wrong. Case in point? The year the mainstream music media awarded Jethro Tull a Grammy for 'Best Heavy Metal Album'.
Your honor, the prosecution rests.
