This Columbia High Fidelity recording is scientifically designed to play with the highest quality of reproduction on the phonograph of your choice, new or old. If you are the owner of a new stereophonic system, this record will play with even more brilliant true-to-life fidelity. In short, you can purchase this record with no fear of its becoming obsolete in the future.
Well, I suppose. It was state of the art of thirty-odd years, and is still fairly widely playable after fifty years. Still sounds pretty good. Not a bad run for a technology.
The music? Pieces by the American composers Theodore Chanler and Lester Trimble (no, I hadn't really heard of them either). On the one hand, recordings of these guys are scarce, and scarcity fosters value--so I could buy this LP on the web for $55 plus shipping. On the other hand, the music is OK but obviously hasn't become part of the mainstream and is mostly forgotten--so I could probably sell it for at most the price of the vinyl.
