If to speak about the progress and the evolution of the... In my opinion progresses from all and is a powerhouse, this is James. In the classical thresh it is already difficult to make progress. The culmination of progress was in the late 80-s. And that what made the world in 90's and 2000's, it's interesting. It is a pity that the rest of the members of this band are not making progress, and engaged unnecessary faeces...
And the vocals... Well, show me one singer, who sang harsh for over 30 years without consequences... And the fact that James drops a tone lower, this is good, maybe we'll see more angry growl, and not squeaky whine of the old man.
The parallel with Chuck, this is of course good, but... this is a separate topic I guess.
