But your 'assertion' that that those buried guitar parts might have been the result of accidentally pulling down the fader at the wrong time is likewise a random one. Why wasn't the faux pas discovered when they played back the Open Reel QUAD master?????
Absolutely agree, remixing a multi track master in the analogue domain had its drawbacks. But a good set of ears and intimate knowledge of the recording at hand would ensure that faux pas, of which I'm sure this is only a small example, would not likely occur.
hey Ralph, i would surmise they didn't rectify it because it was too late by then.
after all, CBS' engineers had already used up expensive studio time remixing it into Quad.
a Quad version wouldn't sell anywhere near as much as the regular Stereo LP anyway, so ultimately i would say the law of diminishing returns took precedence.
even if someone at CBS did discover it had been omitted accidentally rather than on purpose - and it may have been a conscious mix decision, although in this instance that feels unlikely - the chances of an Engineer being able to convince their Boss/Quad Remix Supervisor to spend more money on studio time to redo it feel pretty slim.
