The label of Salsamendi's recording thanks to the generosity of Rob.
Evidently, Salsamendi's recording was very early in the history of In A Mist waxings. See the complete (I believe) list in
Salsamendi was an Uruguayan pianist, organist and educator, as well as an MD. [He taught piano to my nephew Leo Masliah]. I have been alerted by Mario that Salsamendi recorded Flashes in Nov-Dec 1952. This was one of several tracks on an LP (JRG 102) produced by the SODRE (Originally Servicio Oficial de Difusion Radio Electrica, now Servicio Oficial de Difusion Radiotelevision y Espectaculos). Here are the record labels of both sides of the record.
It will be seen that in addition to Flashes, there are three other tunes that Bix recorded, Thou Swell, Sugar and Make Believe (in Selections from Old Man River).
The record was just sold on ebay for $100.
Mario wrote a highly informative article about Salsamendi in his blog. (It is written in Spanish).
