Obviously depends on the genre but, besides the classics ...
Not really.
It's mostly that some things have stood out the test of time, and the newer ones have not gotten there quite as well.
Remember that in the late 60's, even RCA, had the "Red Seal" label, that was used for outstanding recordings, that went above and beyond a lot of styles and things. And there were some magnificent things done ... Alan Stivell's Renaissance of the Celtic Harp ... Tomita's Snowflakes are Dancing ... as two of them I remember vividly ...
In many ways, straight ahead rock, is very limited ... there is nothing for you to add to it to make it better ... and there is nothing "underneath" to make it better and this was something that broke out in those days, and it was one of the things that FM radio, took on ... loudness, instead of fidelity ... and then you had some average music, recorded better, which made it sound way better than it really was, and it was never as good in concert!
Other albums that went above and beyond in quality of recording:
Nektar - Recycled (With Mr. Fast - Synergy guesting on electronics, recording and mixing!)
Robert Schroeder - Floating (LP was originally recorded so you could play it at 45RPM and 33RPM, and it was AWESOME at the lower RPM! Very teutonic!) (Produced by Klaus Schulze)
Klaus Schulze - Mirage (incredible ripping around of various themes)
EgbertoGismonti - No Caipira (Assault on your senses with samba and bossa nova and Villa Lobos!) .. Also Sanfona ... with Academia de Dancas.
Terje Rypdal/David Darling - Eos (Chamber music in space!)
Alan Parsons Project - Tales of Mystery and Blah
Can - Soon Over Babbalooma (Special details are to the low/quiet moments on the two long cuts coming together!)
XTC - The Big Express
Steve Hillage - Green (Produced by Nick Mason!)
The Chef ... Mr. Hayes ... His first album was nice, and Shaft was actually really well done!
And if you get a chance on the Klaus Schulze DVD, there is a special bit with him talking to engineers about details of his recording ... and to hear them discuss WHERE to place this detail and that, and how to make it work, is totally insane! Beautiful too, even though it is so subtle that you have no idea where it is on the real mix! But you know, that the whole thing is a treat to listen to in detail, and that he is no floozy when it comes to mixing, and running his own mixer on the stage! On the stage! While he is playing!
