Unsure if this LP has been discussed before, but yesterday, I received (got back) my original "Led Zeppelin II" LP from my Brother. And, as luck would have it, it's the "RL" Mastered LP! I remember buying it on the very day of its release in Fall, 1969. Now, I've been used to the muddy, echo-laden 2nd Release of this LP for many decades now & hearing the Ludwig 'version' was a REVELATION!!!!!!! I never paid much attention in '69. I'm sure my Stereo wasn't the best. But, when I compared the 2 yesterday, I was blown away at JUST how much hotter the mastering is!! The Bass jumps out at you, the high's are much more 'in your face' & there's very little echo (reverb?) in this pressing. It really was like hearing this LP for the first time!! Get this "RL" version if you can. Don
