I heard some Beatles White Albums are rear
That is a myth. Beatles albums are not rare. They sold millions. There are variations of the original releases that are more desirable than others due to sound quality, but there are still lots of them out there...
"In demand" might be a better way to put it... it seems that everyone with a turntable zeros in on a few artists and they remain in high demand - The Beatles, Led Zeppelin, Pink Floyd, Bowie...
IF you want to listen to The Beatles, by the new mono re-issues. They sound amazing, are accessible just about anywhere you might be and are not nearly as expensive as originals in like condition...
