Yes, I know that the bass is WAYYYY over the top on KE9 pt.3 and it's a bit of a disaster.
I had the chance to chat with Jakko regarding this "snafu" and he basically avoided the subject and was still polite about it.
Here are the facts:
Jakko has ALWAYS done some really good MCH mixes, so , if you have at least half a brain, you'll come to the conclusion that he is a great mixer and would NEVER EVER have done this "over the top" bass part on this mix on purpose, ESPECIALLY on such a seminal album!!!!
I've heard though the grapevine that there were three "aches" you didn't want to have in a studio:
-headache
-earache
-Greg Lake (with all due respect now that he is no longer with us)
Now , MY take is that Mr. Lake futzed with the mix after Jakko had finished it, be it for any reason whatsoever- especially taking into account that even SW bowed out of working with him and that is why Jakko wind up doing the mixing (granted, I have never met neither of them personally, but, Mr. Lake had done quite a few things that pissed me off big time and he thought he was "above the rest"; maybe not at the end of his life but for a loooong time- and I'd consider SW to be a very level headed professional- and trust me, the last thing you want in a recording/mixing session are bad vibes)
So, there it is...why was it that way?, Cause Greg Lake f*cked up the mix on purpose...why? I don't know and it doesn't make sense professionally, but maybe he was already sick and didn't give a flying f*** about it cause he knew he was gonna leave the building sooner or later (yes, I know this is not a very nice thing to say, but , remember, he was a Scorpio, and scorpions will be willing to go down themselves as long as their adversary goes down, and also are willing to sting themselves to death... and to quote the great Cervantes: "vale" )
