Maybe I'm misunderstanding you, but there are several extant performances of it from 1979. E.g.

I'm in the lowest tax bracket, but I guarantee the taxes I pay hurt me more than someone in the highest bracket because my living expenses are a much greater percentage of my income since I make so little money.

And I'm still happy to pay my taxes because I'm not a piece of shit.

Also there and my first Sisters gig. Will have to check my 1990 diary later, but If memory serves it was the night after seeing the Happy Mondays there too.

Not at all :)

There are also more objective ways to rate the albums - production values, innovation, influence, etc. And these can clash with subjective views. For instance, for me Disin is objectively a better album than Porn, but Porn is so special to me personally that it can't be topped.

We do, but in the short term at least, as well as there being some variability, there's also some stability. For me Porn & Disin are never gonna slip to near the bottom and selftitled & 4.13 are never gonna rise to the top, right? So there's still (subjective) value, even if not complete accuracy
