Tango is a musical genre that I have an appreciation for - and there are a few 1930s tango recordings in the Radio Dismuke playlist. Tango music was extremely popular in Germany, of all places, in the late 1920s and early 1930 and I actually prefer German tango recordings from that era over the ones from Argentina. And recently I discovered via recordings people have posted to YouTube that tango was apparently also popular in Poland during the same period.
Today I stumbled across two radio stations in Argentina that have a tango format and stream online.
FM Estereo 2000 I listened for about an hour and the vast majority of their selections seem to come from vintage material. A number of them I thought were VERY nice. The stream is dial-up friendly - though the audio quality on some recordings is a bit on the low side for even a 24 kbps stream. To tune into the stream, click on the "En Vivo/Live Here" link.
FM Tango Rosario This station also features vintage tango recordings in its playlist. At 56k, however, the stream will not work for those on dial-up. The audio quality of the recordings is much better than the first station's. Unfortunately, this afternoon, the station streams ONLY from my left speaker. My guess is they have an incorrect setting on their streaming software - and hopefully someone will notice adjust it. Since the recordings are mono, the stream coming from only one speaker does not impact the music quality - but it is a little annoying. To tune into the stream, click on the "Radio Online" link.
