Don's voice is nowhere near its prime any longer, but its also better than it has been in quite a few years now. The thing I'd be concerned with is that Lynch can barely play his solos even remotely as well as he used to. I admit I'd probably go to see them though regardless, it's freaking Dokken after all.
That's one instance, there are countless others where his phrasing is worse than Lil Wayne's on a crack bender, and he flubs note after note. Jeff plays Lynch's own stuff better than Lynch has in years.
This rant contains a perfect example:
Skip to 3:20.
Don's voice isn't quite what it was in the 80's, and it did take a horrendous down turn in the 2000's, however, "shot" is the absolute last word I would use to describe his voice as of right now:
A live show, yes, but a rehearsal gig, not a full-fledged performance gig, so in a way, it was a bit of a glorified soundcheck. If anything, he's smart for not pushing himself at a rehearsal.
I'd like to know how explaining the basic circumstances is "excuse making".
Oh, I agree it doesn't excuse them not making the effort, especially Don, but I was just explaining why Don didn't sound as great, that it was down to that and not him being incapable. He also did injure his voice around the time of the show, so an all the wiser move to lay it back if you ask me.
