Great sounding WLP LPs.

what is WLP?

I asked myself the same thing. I am assuming that WLP stands for "White Label Promo", but I really don't see what the OP is asking? Most records had a release as WLP for a small, first batch to the industry.

If it is White Label Promo, then OK.
I have a few promos which have some unique feature.
I like the QuiexII promos I own the best.
Then i also have a few of the white lable variety, and a few colored vinyl types. (where only the promo had a unique colored vinyl)
As for if they are better, not. Exception being the QuiexII.
The one advantage of old promos is they most likely were played less. Having been in some DJs collection for many years, just sitting there.

I have several WLP's and they can be fantastic, however many of them have been played extensively and are noisey, though even those can be better than a quieter regular pressing. A few titles that come to mind are Born to Run, Darkness on the edge of Town, Billy Joel Turnstiles (excellent).

It's (funny) that my response to "Tbromgard" several days ago, was never posted. Oh well, it's not the first time. I'm kind of the persuasion of Tom Port @ Better records. I have heard for myself, the difference between pressings of the same lp. This is why I (asked) others of their RECOMMENDATIONS for WLP. Knowing that these arer sometimes tipped up in balance, there are some that exceed normal pressings.

Ther, I did it, I explained myself!
