Hi Art,

Lawrence Gellert recorded African American protest songs on 61 zinc Echo discs in the late 1920s. I seem to remember that Gellert's brother worked for Echo and that's how he managed to get his hands on a stack of them. In his notes (held by the Indiana University Archives of Traditional Music), he claims that he managed to capture decent sound on them, but he had to jerry-rig a Victrola to make it work. Unfortunately, he also says that one of his assistants ruined the discs by storing them in a stack during the transcription process. 

The discs were transferred as part of the first stage of Sound Directions and every once in a while I was able to make out an occasional word or enough of a melody to tell it was the same as one Gellert had recorded later on an aluminum blank. In any case, Gellert's notes would have the recording dates and additional information about obtaining and recording zinc discs in general. Also, the ATM should have info. on the styli they used to do the transfers, although I believe they had them custom made.

| These zinc Repeat-a-Voice, Echo, Rekordo, etc discs used an entirely
| different premise than the plastic Victor Home Recording Discs which
| had a narrow groove widened at the top by a rounded stylus. Those
| occasionally have good recordings on them. The zinc discs would have
| dimples lightly embossed lower in the groove by a regular steel needle
| which was supposed to be the same one to play the record back.  They
| never intended you to be able to play them later on.  You would really
| reused them.  If you have them and an acoustical machine you can try
| them out yourself and hear that they replay practically nothing.
| Shiffy, I first reported on these so long ago it appeared in Lenny
| Kunstadt's Record Research magazine at least 35 years ago!
