Great sounding/recorded albums

I can see that @tostadosunidos. Those Southerners have an unfair advantage ;-) . Have you heard Patsy’s very early recordings, before Owen Bradley began producing her? She was much more Hillbilly early on, almost Rockabilly (as were guys like George Jones and Johnny Horton, and the great Wanda Jackson, whose two recent albums were produced by Jack White!).

Another great early Rock ’n’ Roll act recorded in good sound were The Everly Brothers. Both their Cadence (late-1950’s) and early Warner Brothers’ albums (1960 onward) possess good recorded sound, especially on the Ace Records (UK) LP’s pressed in the 1980's.

As roberjerman suggests, a direct-to-disk LP. Once you've heard one, everything else sounds veiled, compressed, and lifeless. Sheffield made a bunch of them, both Pop and Classical. There are other d-2-d labels, but the Sheffields are easier to find and cheaper to buy. You may not like the music much, but for sound they are unmatched.

For albums made with a recorder, the releases on the Water Lily label possess instrumental timbres as natural and sonics as transparent as have ever been recorded onto tape. I suggest "A Meeting By The River", acoustic guitar by Ry Cooder.
