Description
This two sided 10″ record features soprano with orchestra in Italian, Frieda Hempel, and with violin obbligato by Mary Zentay
This is one of the 1/4 inch thick black carbon Edison records, with the earlier etched information instead of printed label.
Edison Diamond discs were recorded at 80 rpm is using a horizontal diaphragm, so intended it to be played back on an Edison phonograph that also used a horizontal stylus/cartridge that Edison referred to as diamond tipped.
It should not be played on any of the steel tip vertical diaphragm stylus players of that era. They will destroy the up and down modulated groves as they are meant for side to side modulation.
