All too often it is forgotten that Arthur C. Keller of Bell Labs was
doing stereo recording of the Capitol Theater Orch as early as 1927
(those masters seem to have been pilfered from Bell) and with Stokowski
and the Philadelphia Orch in 1931 and 32, stereo starting in March 1932.
 Some Stokie recordings were issued on 2 LPs by Bell Telephone Pioneers,
and Ward Marston announced at ARSC NYC a few months ago that he is
planning on re-doing those recordings because he can do a much better
job now and that he was never satisfied with the LPs -- his tapes
sounded a lot better.  Although the Keller stereo recordings were two
groove, he was also working on a single groove 45-45 system for which he
was awarded patent 2,114,471.

Hi Don:

This seems to be the recording of which you write:
http://shop.lpo.org.uk/shop/recordings/detail.asp?5004,0,0,0,0

I listened to the sound sample, which is allegedly a "stereo" and to my
ears, the music is coming 
just from the center (ie mono) but there's different disk surface noise
on the left and right sides. 
I've heard more impressive Blumlein stereo, I think in a BBC radio
documentary. Is there anything 
better on that CD?
