My criteria for the selections on this list are pretty simple: Analog LP recordings that are justly famous and culturally significant. That said, the list is admittedly arbitrary. I have squelched my own preference for field recordings and experimentalism, but still tried to present recordings that have authenticity and genuine musical interest. If something of the packaging is interesting too, so much the better.
Audiophiles and music lovers will quibble with my choices, and I applaud that. The more discussion the better, as it only means more good music will get recognized.
You can find many of these titles online far more easily, and generally far cheaper, than in record stores. But use your head: LPs wear out and scratch easily. Covers and sleeves are easily abused cardboard and paper. Hint: A first-issue Beatles album selling for $10 is probably ready for the trash.
