LP
In Through the Out Door
South Africa, 1-Song (N/A) Acetate

Here is a very interesting 10″ acetate from South Africa dated September 17, 1979 for the song Carousal (Alternate Edit).  One has to assume this if for Carouselambra from In Through the Outdoor.

Acetates. or better known in the industry as lacquers are the first step in the physical manufacturing of a record. They are lacquer-coated aluminum discs and heavier than commercial records and usually one sided. 

Acetates are made for two purposes, to evaluate a recording and its suitability for pressing records and to use in the production of the finished product itself. There are never many acetates made during production, usually no more than 10, which make these pressings very sought after.
