I remember hearing a horrendous second Queen of the Night aria ("Der Hoelle
Rache") on an EMI collection of *Les Introuvables du Chant Mozartien*,
which, on the basis of posts I've read now and previously, I assumed had
been by Mme.  Jenkins.

It wasn't.  It was by Maria Galvany.  It sound like a 33 rpm lp played at
45 or 78 rpm.  The liner notes describe the rendition as "both curiosity
and monstrosity...show[ing] what idea of Mozart was current at the time!"
In the performance's feeble defense, it was recorded in 1906.

Does anyone know more about Mme Galvany and whether she should be taken
seriously as an artist?
