Usually contain live concert recordings but may also contain interviews, unreleased songs or studio outtakes. Usually manufactured for special occasions or one time use. This section also contains a group of discs known as the Century 21 discs. These titles were made in multi-disc sets for sale to radio stations only. Sets were made for various musical styles such as AOR, MOR or Country.
All titles are various artist discs.
Sets came in red on silver, blue on silver or black on silver. Later releases used a special noise reduction system and were termed 'Gold Disc 2' or 'Gold Disc 3' depending on the noise reduction system used. Disc colors were black on gold on an aluminum disc. Many of these items have reached the collector's market. No distinction is made here for the various releases and most command the same price.
