[78-L] An odd Emerson

[Robert Shirer]

Hi all,
I found Emerson 02036-X among a bunch of records that I had never gone through.  Black label with a red background to black Emerson lettering, highlighted by white.  Mx 4178 is the Bell Song from Lakme; mx 4179 is "Caro Nome" from Rigoletto, both sung by Eva Leoni, with an orchestra accomp. conducted by Arthur Bergh.  Some impressive vocal calisthenics. Curious about the singer, the recording (when, where) and whether this is an Emerson line with more of similar material.  It is certainly different that the typical Emersons I have found.
Before I sent this, I checked Ty's online discography site.  There seem to have been quite a few "2000" series classical discs.  Did Emerson get them from elsewhere, or did they record them themselves.  I've just never seen one like this before.
Thanks in advance.
