Julio Martinez Oyanguren, “Aire de Zamba”– 1936 (aluminum record, transcription disc)

This is a live radio broadcast recording of the Uruguayan classical guitarist, Julio Martinez Oyanguren, playing a song written by a Paraguayan classical guitarist named, Agustin Barrios Mangore. The track was recorded, via WJZ Radio, onto an aluminum transcription disc during a live performance for the Pan American Union Concert held on April 4, 1936. Aluminum records are quite rare, owing to the fact that most of them were melted down during the scrap metal drives of WWII, and also because aluminum proved to be a very poor recording medium and was quickly surpassed by lacquer coated discs.
