Pantera is just blues rock with a much heavier feel.
Where to even start ... With all due respect,
oh, man.
So Pantera is a blues rock band, is it?
I suppose about half of all trad metal groups are really just blues rock, too, then, eh?
This is where I get off the train. Further discussion is pointless.
P.S. That "Mouth For War" tune, what a wonderful tribute to the blues stylings of SRV. It has so little in common with extreme heavy metal, after all. And "Fucking Hostile" is essentially a blues jam. "Strength Beyond Strength"? Total blues, just played in a heavy way.
