All this talk remained me, I've got a Black Sabbath Heaven and Hell (Dio) Bluray, I've been saving for just the right moment, haven't even opened it ... then I forgot I had it, embarrassing ...
Love the Dio Sabbath years.

The tech 20 years ago, should be able to hold up well actually (I'm amazed at what was captured at Woodstock, and other wild festival environments of 40 plus years ago).
There's one element that really helps with superb audio translating to later release, that's isolation and triggering. Triggering allows the absolutely perfect drum sounds, and live work, captured for such "statement", really benefits. You don't want to high pass some of your drum mics ... but high levels of LF contaminate the tom and kick drum mics. Triggering, eliminates much of these issues.
Question, the Metallica Through the Never, is this from an arena "in the round" tour? If so, they used the coolest subwoofer array, the TM array. It suspended (80)18"s, in a 10 box high vertical line array, directly above the stage. Simply due to cabinet spacing, the array keeps huge amounts of LF off the stage below, a simple elegant solution.
Anyway, these types of tech advances have certainly increased the quality of both the live event, and any A/V capture.
