No I get that point. Honestly I doubt very many people disagree with you in that studio albums are better than live albums/studio renditions are king,
Then I'm one of the few who strongly disagrees - at least in some specific cases, though most of them being non-metal artists. I already mentioned one of these cases in my first post in this topic, namely Mother's Finest. At least the live renditions from their Rockpalast-concert in 1978 and on their "Live"-album are far superior to the studio versions.
Another prominent example - though I don't listen much to her anymore - is Tori Amos. This live version of "Father Lucifer", in which she incorporated excerpts of "Tubular Bells" and "Small Town Boy", is IMO far better/more interesting than the studio version:
My favourite album by her is a live-bootleg (with excellent sound quality) titled "Saint and Sinner" from 1996. It's a concert where she was just accompanied by acoustic guitar, just like the concert on her official live-videotape "Live From NY" (don't know if it was ever released on DVD).
Other examples are my two favourite Norwegian live artists, Mari Boine and Kari Bremnes. In the case of the former, compare this original studio recording
to this live version (yes, I posted it recently in another topic)
and then try to explain to me why the former is better than the latter. I really do like the studio version, but this live version is far more impressive.
Or compare this original studio version (which I really do like a lot) of one of my overall favourite non-metal songs (it's from 1993)
to these live renditions from 2010
and 2018
OK, only the vocalist remained the same and the keyboard-player on the two live-renditions. And different musicians interpret songs differently, which becomes quite obvious if you compare the improvised guitar-solos in the two live versions. Personally, I prefer the version from 2010, also because of the drummer.
As far as metal is concerned, there aren't many live-recordings which impressed me. But there is one exception to the rule, namely my currently favourite "old school" metal band Lovebites. I couldn't name one single song from their studio albums I like better than the version(s) on their official live-recordings. It seems I'm one of very few people here who like them, so I'll pick one of their thrash metal songs (whose main riff reminds me of Testament's "Over the Wall" - only I like Lovebite's song better) and their only "proper" ballad to illustrate what I mean:

Now try to explain to me why the studio versions are better! They aren't, not even production-wise.
