I have the original RCA Belafonte at Carnegie Hall and the Returns to Carnegie Hall and the recording quality is superb. I've heard the Classic Records reissue and that too is good. The Ella "Clap Hands Here Comes Charlie" is another original that I have that is good sounding, but I like the sound and music from Ella Fitzgerald and Marty Paich and his Orchestra: "Whisper Not" even more.
Another late 1950's stereo recording that is shockingly good sounding is "Satchmo Plays King Oliver." I don't have the rare original, but, the reissue I have sounds great. This has a great version of "St. James Infirmary" on it.
