Is this Normal? Zeppelin IV LP sounds horrible

The whole albumn on every release is made on a master that is very much intended to sound distorted. Extreme distortion was the mission for this albumn and so you simply failed to do your homework. Evidently you don't have the insert that reminds you to smoke a substance rarely herd of in the sisal family of plant genera until not feeling quite right. It should then be followed by eating so much food that you become nauseated. It was meant to be an art dynamic which involves listeners do as instructed. Otherwise it has no meaning and you are not going to understand the sonic element out context. All published versions require that you do your part. Some even recommend using equipment that is almost in need of repair and will enhance the distortion and always put the volume on 11 or twist it beyond the minimum attenuation. This makes the distortion very pronounced and as long as the blown speakers which you must buy at a thrift shop make sound you will get the point.
Everything from a lousy cover band version to Capitol's test pressing gifts to the producers, the very first A1 A1 hot stampers, all achieve the same important milestone in the cutting edge of creative musical art.

Mechans: if there's a bustle in your hedgerow, don't be alarmed now...

Mechans, I hope that was meant to be a joke. I don't know if you play or have ever played a guitar, but you are clearly confusing good distortion with noise. The organ is not meant to be distorted ! How does your argument hold, when much of the surface noise is due to pieces of paper and sand in the recycled vinyl. That has nothing to do with the master tape, or "homework". I am glad it was done on analogue equipment, like all good recordings, but I am not speaking of noise floor. I am speaking of horrible clipping and even surface noise that doesn't sound good to anyone who has done their homework or not, with the exception of you. Why delude yourself into thinking that it was intended to sound bad? Does this absolve you of some guilt for buying poor sounding records? That is foolish. I hit a record spot near by and heard a japan issue, sounds incredible! The fact that Jimmy Page would occasionally insist on single runs is not even a valid excuse, as much can be done later in post production to fix many of these issues. That is really not it at all, this has to do with cheap pressing and recycled vinyl, period. I would like to hear others weigh in on this; if I am wrong please speak up. I would like to learn, but please provide a valid and logical argument.

How could extreme distortion be a goal when you have slow melodic songs on an album. This is not ACDC or Metallica.

LOL! look at all the new releases and reissues, Even page realized he could better the old classics! Case in point Mothership. Just thought I would add that in.

D I just saw yr OP. I have a European pressing. Haven't listened to it in aeons but, still, don't remember the kind of distortion you describe. Must check it out.
BTW, Mechans, I have other LZ too, they're not particularly hot on fuzz boxes, etc (which were used in 70s psychedelia).
