As I see this exericse, in an ideal world this should be about the ear, not the gear. The point should be (IMHO, FWTW) not whether they used a Neve or a Mackie, but rather HOW they used it to make the recording, and HOW one figures that out by actually critically listening to the recording.
The point of this exercise - as I see it, anyway - is not to pick a genre or a song and give some recipe for how to do it; recipes don't work that way. Two albums by the same band are often done entirely differently, let alone same genre. Hell, often two songs on the same album are done entirely differently. There is no recipe.
I think it would be of far more value to take these recordings and be forced to HEAR them ourselves, to actually LISTEN to them. Them figure out and discuss WHAT do we actually hear, and from there deduce perhaps WHY we hear it. Not just the gear, but how it was tracked and how it was mixed, and why it sounds like it may have been done that way (e.g. what did the producer have in mind when they gave that instrument that property in the mix?)
Keeping our ears trained to "listen like an engineer" and to be able to forensically analyze what we hear will go a much longer way to being able to produce our own sounds the way we want - as well as perhaps give us a few more ideas - than any magic recipe or printed production recollections will.
I'd also like to point out that when it comes to many of the finer and final attributes of a recording, much depends upon the source we are listening to. For example, that Walter Egan recording is one that is available from *many* different compilation and anthology CDs, each with it's own ME, each with it's own source recording, each with it's own decisions as to how much to master/remaster the recording, and each with it's own print to glass master. Not to mention different MP3 encoders and settings should one be listening to an MP3 version. Gotta be careful on some finer points ("that guitar is lacking the punch") that may be as much a result of the mastering version as anything else; and maybe cite the source which we are listening to when we give our analysies.
I do have a candidate song or three for analysis that I think would make interesting and useful discussions. In the meantime I'm still trying to get that Egan tune on my system...
