Rarities and Reissues: Blue Note Records Turns 75
One, the original pressing (mono or stereo), is an artifact, an insanely valuable antique, the object of fevered jazz collectors the world over.
The other is a fresh vinyl reissue, cut from a high-resolution digital remastering of the original master tapes, that's meant to bring in younger listeners, or those interested enough in the music that they'll pay $19.95 for a new LP.
