Some of the artists were more famous names working under pseudonyms, but more were honest-to-goodness working musicians who may not have been glitzy, but who turned in a musical and professional performance.
The wonderful people at Rediscovery lovingly remaster these old recordings, often from reel-to-reel tape. They make their polished products available for a mere five bucks an album to download, and furthermore they make a whole slew of recordings available for free – their paperback classics section. The paperback classics are recordings they tried to refurbish but that didn't meet their rather high standards!
So head off, dear reader, to Rediscovery and check out their catalogue.
Of course, you can ram-raid their Paperback section, but spend a few bucks on their commercial restorations too. Encourage them. They are crazy!
Don't forget to try Fou Ts'ong playing Mozart concertos. It's free – and splendid playing!
