all titles had been issued at same time span with use of available in their time equipment still greatly varying in sound fidelity.
unfortunately the most selling acts, usually had worst quality of sound and often mixing performance. go back to 70th,
Led Zeppelin, Deep Purple, Black Sabbath, Uriah Heep, Queen, etc. perhaps most significant examples. no single album
with decent sound.
seems like only the bands where musicians were involved not in playing only but recording/mixing too or was lucky enough to
have engineering personel who's cares about sound, had left enjoyable sonically releases.
you really feel that there are no albums by Zeppelin, Sabbath, DP, or Queen from the 70's that sound decent?!?
good grief! what's your point of reference?
the original vinyl? the first cd pressings? the remastered CDs? MoFi reissues? high-res/5.1 releases?
I could name a good half a dozen excellent-sounding 70's Queen, Deep Purple, Sabbath & Zeppelin albums on various formats.
The DVDA of Queens' The Game is superb, the SACD quad and DVDA 5.1 remix of DP's Machine Head both sound excellent, the stereo remastered cd of Paranoid is surprisngly good (the quad transfer in the Deluxe Edition is awful though sadly) and the original "target" Barry Diament mastered CDs of most of Zeppelin's albums are really very nice and I never feel when listening to any of them, particularly in relation to my original LPs, that they are of poor fidelity.
Every one of those acts have their albums that appear not to be as well-recorded as they could have been, admittedly.
For me, Queens' A Day at the Races was never that great a recording to begin with, Zeppelins' second album has a good few overloaded/saturated parts with bass distortion etc and perhaps the quad mix of DP's Stormbringer lacks some top end fidelity and bass stability but as has been said, in the context of the era these Moodies albums were recorded in the majority of them hold up well, IMHO, as do the majority of Queen, Zeppelin and Deep Purple albums.
