I wouldn't say so, JP.
Unfortunately I think there's actually a common ground all over the NET:
Sure, if you like it you think there are differences, periods, hues and nuances.
Same thing that happens with a genre you like, say, heavy metal.
It sounds all the same to me but oh, go tell a HM lover!!!
They distinguish death metal, hard death, gothic death, gothic, gore, death gore.
And wrath upon you if you can't hear them all different!!!

I think there are different Dylans, sure.
60s, then 70s, then Xan period, then the rocker, then....the NET.
And in the NET, to me (and to me only!!!) it's all crooning, downhill vocals, flat arrangements.
Yes, surely Milan 89 was another story.
Sure The Supper Club is no 2006.
But at the end of the day they all sound similar to me.
I respect your high opinion of the NET and I think tha not *getting anything* from the NET is *my* problem.
But no, there's no live Dylan I'd save after the Tom Petty tour in 87.
After that, it's all too *old*, flat and *soft*, to me.
