The Seeburg Encore records were made between 1963 and 1968.
Unfortunately, I couldn’t find a list with the manufacturing dates of the various records anywhere.
As with the other Seeburg 1000 records, no track list is available for the Encore Library.
These records have a large 2“ center hole and are approximately 9“ in diameter.
The Seeburg Encore Library Supplement was introduced in April 1963 for use in cocktail lounges and restaurants.
Although the Encore records were still essentially Easy Listening instrumentals,
they were considerably jazzier than Seeburg’s other background music series
and the tracks featured impressive instrumental solos.
The Encore records featured extended frequency response and a wider groove cut.
They sound every bit as good as standard mono LP records of the period;
in fact it is safe to say that these are the best sounding 16 rpm records ever made.
A new version of the Seeburg 1000 was unveiled at the same time.
It was called the Encore Phonograph and unlike the previous versions of the 1000,
it was housed in a handsome Danish Modern cabinet and intended to be in public view.
The Encore Phonograph and records were sold to customers outright rather than leased.
At $695, the machine was hard to sell because few customers were willing to plunk down that kind of change
in 1963 for a phonograph for proprietary records (the records can only play on this phonograph).
After a few years, Seeburg pulled the plug on the Encore series in 1968.
Consequently, these records are scarcer than your standard issue Basic, Mood, or Industrial records.
