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. (More.)
