@tylermunns: Good news! Analogue Productions has reissued the debut Buddy Holly LP, and it is spectacular! Considerably better than the version issued by MCA Records in 1988. AP has issued the Crickets LP as well, and it is not far behind.
As for the From The Original Master Tapes LP on MCA, if you go to the credits on the back of the cover (near the bottom), you’ll find this statement: "Digitally transferred from the original stereo and mono master tapes." That LP was issued in 1985, when digital was still in it’s infancy. I own it for the music, not the sound.
And if you like 50's Rock 'n' Roll in general, The Everly Brothers were also recorded well. I have originals (on Barnaby and Warner Brothers), and reissues done by both Rhino Records and Ace records (a great U.K. label), and they all sound great. Fantastic music too, of course. No Everly Brothers = no Beatles. ;-)
