More great recordings made in non-"pro-quality" environs:
David Bowie - "Heros"
Iggy Pop - "Lust For Life"
Talking Heads - "Stop Making Sense"
Bob Dylan and the Band - "The Basement Tapes"
Most recordings made for "MTV Unplugged"
Pete Townsend - "The Secret Policeman's Ball"
Most "Soundstage" recording releases
Most stuff recorded at Chess records
The field recordings of Alan Lomax
Various Newport Jazz and Folk festival recordings
And, speaking of field recordings, there was that little one in that cornfield in northern New York state in the late 60s...
As far as your comments re "Exile", why does not hearing bass (or any other) problems automatically make it a pro or a great-sounding room? It was a mostly un-treated basement of a French castle. Hardly the definition of a great-sounding "pro" room.
The fact is, there are a lot of more-than-adequate-but-not-necessarily-great rooms in which great recordings can be made that are not necessarily something that anybody would consider to be "pro quality". And that's even if one ignores my personal definition of great recording and just looks at the technical aspects of the recording.
Look, friend, we can go round and round on this and get nowhere, because we have two different definitions of "great recording". You have the ability to separate the sonic quality from the content and consider a recording great based solely on the sonic clarity. I am unable to do that. I view a "recording" as the total of it's parts and am unable to separate the sonic quality from the content. For me the original recordings of Robert Johnson sound a lot better than your average modern day Ry Cooder recording (with some exceptions).
Which one of us is right? We both are. You're right for your definition, and I'm right for mine. The OP opened this thread by positing what is basically the same definition as mine. I and others agreed. You and others disagreed. Let's move on, shall we?
I don't care how good a recording you make of someone vomiting, I'm not a foley artist, nor is this a foley/sFX board. And even if I/it was, is a sonically pure, perfect recording of someone spewing in a great live room really what the foley artist wants? Not if the scene he's trying to dub is of someone yawning outside or in a tiled bathroom or in a million other locales that are not the live room of an L.A. studio. Either way it's something that'll never make my list of "great recordings", because the content is simply not enough to push it that high, no matter how great the tech aspects of it may be.
