The goal of this website is to explain the complete manufacturing process of records and CDs, especially how matrix codes are inscribed and what they mean, and apply the information to explain official Nirvana releases, such as deciding the time and place of manufacture, verifying authenticity, and even understanding why certain items were made. The site covers test pressings and Pennyroyal Tea items.
For a complete discography, please visit sliver.it.
The list below shows all the new items and items which have been updated with new pictures, but if you have some time on your hands and an above average interest in test pressings and matrix jerking, I suggest you look around a bit more. Every page which has more than one paragraph of text has been significantly improved, not to mention corrected. There were a lot of errors on the old site. Also, The Muddy Banks CD-R has been removed from the in-house reference list (which are now called samples), as it is just an advance CD-R promo.
The following other documents are worth reading again: Vinyl manufacturing has a good matrix code example at the bottom; Test pressings has new information regarding test pressing noise and CD samples; Mastering studios has new information about Abbey Road which may or may not have cut the Geffen singles after all, as well as a new section about Heathmans Mastering; MPO wrote their own matrix codes; Sonopress now features correct information; Sony Music is a new page about the Dutch pressing plant; The Optical discs pressing plants pages no longer contain false information (hopefully); Pennyroyal Tea single has been reduced from 2200 to 1100 words and is now possible to read, not to mention it is more accurate; Bleach RE-1 and RE-2 test pressings are much better explained; The marbled white Bleach test pressing now has a purpose (hopefully); The Hormoaning test pressing is still the only one.
The ORG test pressings will be added soon, and hopefully Ross' friend will return alive after his mad festival spree to send me a better picture of the Unplugged In New York sample CD which is shown here in a hilariously poor photograph taken about ten years ago.
