Any rock fans out there?

@ Captain_winters: I do have the UK WWA of 'Paranoid.' I found it to be better sound-wise than the WB green label. I also have 'Never Say Die!' on the UK Vertigo label. That sounds good too. All the other ones with Ozzy Osbourne on vocals I have on the Warner Brothers label. These are all originals, as far as I know. So, if '13' is that good, I will buy it. Hell, I was gonna buy it anyway! Now I have no doubts.

Cheers Dave....BTW, MRA refers to Mould Release Agent which is a chemical embedded in the vinyl compound to prevent the LPs sticking to the mould when they are manufactured.
There used to be a great debate, years ago, about whether to clean the stuff off the surface after it had settled (apparently vinyl can continue to "express" MRA for year/s afterwards...)
Some felt it acted as a stylus "lubricant" and refused to clean it while others maintained it was destructive/obstructive and must be removed at all costs.

The latter argument is probably a safe bet however it doesn't always manifest itself in an intrusive way. It probably depends on whether they got the formula right? (I'm no chemist so I hope those that are will forgive any misconceptions on my part - and should feel free to add to our knowledge on the subject :)
On the other hand, occasionally, I've seen/heard LPs that actually sounded damaged(!)- mistracking severely on peaks etc - and the only explanation was MRA. Once this was thoroughly removed the LP would play flawlessly.
All the best.....

Oh ok, thanks for the explanation on that. Hmm...yeah, I just might have records like you described. What is your method for cleaning, may I ask?

Dave_72,
I use the AIVS 3-step regimen on new (and used) records. The first step is pre-soaking with the Enzymatic Formula that helps remove any release compounds. AIVS also makes Formula 15, which is designed for tough cleaning jobs, including removal of the MRA. I highly recommend AIVS products. I've been using them for years now and I absolutely love them. Jim Pendleton, who is the designer and owner of AIVS, also sells record cleaning brushes through his company Osage Audio, and I think they are the best brushes on the market. I have no affiliation with Jim other than a great experience as a customer.

Regarding Bill Ward, my understanding was that there was some sort of a contractual dispute that resulted in him not participating in the making of the new album. Interesting that you heard it was related to his drumming.

Dave,
This stuff (LAST Power Cleaner) is proven to work on MRA...
