Direct Metal Mastering ( DMM ) LPs. What is this?

I have quite a few of the Stockfish LPs and find them fantastic.  I also bought a few of the Rush reissues and there are fine.

I know I have several other DMM LPs and can't remember them being anything but good.

Momentary Lapse of Reason is DMM mastered and sounds super great.
Many records would have DMM etched and not mentioned on the album cover. It was popular method of mastering in 80's. Even some disco albums found in good will for quarter maybe DMM. Not a biggie in terms of value, but sound pretty good in almost all cases.

Momentary Lapse is absolutely boring music....also he's clearly Anti-semitic.  

Stringreen, I completely concur to your statement and don't care much about the music. I only described one of the highlights in DMM mastering in this particular album. 
I also intend to examine weather any statement is antisemitic or not. A war causing damage of any casual population by any side to control the territory or resources I would never justify no matter what side is taken. Also note, I was born in Jewish family, but prefer to be religion free.
Statistically and factually no Pink Floyd songs and albums ever motivated any kind of depopulation of any kind or feud between different nations alas from Badenweiler March(for example) so considering any of them anti-semitic may not have any valid point.
