You are asking about LPs or CDs??
There is a completely different reference on both mediums so i'm posting here my opinion on both. These are strictly personal choices after 30 years of collecting.
LPs
The Lps listed below are only a few of the rare and precious vinyl releases. I could add 100 or 200 more, including EP releases (the invaluable CAM CEP series, or some french Barclay, Vega and Philips releases such as LES YEUX SANS VISAGE by Maurice Jarre, that was released on Vega label with 6 tracks that I have never ever seen a cover).
