Appalachian Spring

That's probably the Columbia recording Rushton refers to.

I'm afraid I'm all digital here. Can anyone comment on the Sony with Copland conducting?

Thanks!

Thanks for the recommendations. The only recording that I have is a 1987 London cd of a 1976 performance by the LA Philharmonic; very engaging but I want to get a full analog LP.

The Reference Recordings LP is a great recording of the original chamber orchestra scoring of Appalachian Spring (13 instruments). I've come back to it regularly over the years. For a full orchestra performance, The Bernstein/NYP on Columbia is excellent as is the Copland performance also on Columbia. I like the Dorati/LSO performance on  Mercury, but it doesn't quite get me at the emotional level like the other three mentioned.

The RCA recording with Copland conducting was the one I grew up with, I still listen to it.  I thought I saw it reissued, maybe by Analog Productions, but I don't see it anywhere so maybe it's a possible future reissue.  The originals should be out there in used bins, though.  I note that RR22, mentioned by Folkfreak, is the original version for 13 instruments, not the full orchestral version.  It is a different take on the piece, but a good one to have in the collection.

You could try Reference Recordings RR2, great sound quality but some find the performance a tad slow. In any case it's an excellent recording
