What a load of pretentious twaddle. If that's the case anyone, armed with a decent backing band, can get in front of a microphone, belt out some unintelligible rubbish, and claim it's "art".
Yeah, mate. They can. People do it all the time.
Whether you like the art is a different question, and the answer is completely up to you.
That said, to the rest of your post . . . I have offered my staunch opposition on this thread to greatest hits and live records before, because the scores in context will almost definitionally be higher than original records. That's why artists produce greatest hits and live records in the first place.
In my own personal ranking of favo(u)rite records, I have separate categories for greatest hits, live records and EPs.
Bluntly, we shouldn't allow them here. That should be part of the rules.
So as much as I like this, when I score it I will will dock it a point to offset the natural grade inflation.
For the record, this is my favo(u)rite live record, my favo(u)rite greatest hits is the now-unavailable-in-any-form Lynryd Skynyrd album Gold and Platinum, and my favo(u)rite EP is REM's Chronic Town with an asterisk for New Order's 1981-1982 which is more a mini-LP than an EP.
