Interesting Mercury-centric note on this. The first Mercury session to make it to commercial stereo 
release was November 1955 in Minneapolis. There had been many experimental recordings made before 
that, trying various things in 2 mic/2 channel and not being satisfied with the results. Mercury got 
its first Ampex 3-track sometime before November 1955. The Bartok Second Suite, recorded 11/26/55, 
is the earliest Mercury stereo recording put out on record.

Now here's where it's interesting. Also recorded that day were Beethoven Symphonies 4 and 8. But, I 
find no record of a stereo tape in the tape library as of the 90's, and those works were never 
released on LP in stereo. This makes me wonder why they'd run the stereo recorder only in the second 
part of the day? Maybe equipment issues, that's all I can figure.

The Second Suite was released on CD paired with the Bartok Violin Concerto #2 with Menuhin, recorded 
at Carnegie Hall in 1957. That recording is unique, too, because it's the only one I can find where 
Neumann KM-54 mics were used on the sides (KM-56's were used most of the time from early 1956 until 
1959 when the switch was made to three Schoeps M201s. It's also the only Mercury Living Presence 
recording made at Carnegie Hall, as far as I know.
