There has been many a debate about Pantera stealing other bands sounds...Meshugga (spelling), Metallica, ect... but if you listened to any or their albums youll see that they pregressed heavier and heavier from one album to the next...I believe they have their own sound
But my favorite albums has got to be Far Beyond Driven and Vulgar Display of Power.
I believe that they had great influences that created their "power metal"/"power groove" sound...Metallica, Sabbath, ect
And if they say that there are many bands that stole Pantera's sounds, I find that not the case....they are just heavily influenced by Pantera- ie Killswitch Engage, Avenged Sevenfold, Atreyu, ect...
But one thing is for certain...there will never be another Diamond Darrell (Dimebag) or Phil Anselmo ever...there will never again be another Pantera...
