I realized that I hadnt posted any Juana.
Juana Molina kind of invented techno-folk in Argentina.
After a run as the Gilda Radner of Argentina, doing a dozen or two characters on sketch comedy on TV for years, presaging Portlandia by a decade or two, she retreated to her shed in the garden and started looping, singing, strumming, and making music.
I have seen her live a few times, and she is mesmerizing to watch, as she constructs music out of seemingly nothing, alone, weaving a web strand by strand. I have seen her play with a rocking rhythm section, too, and once saw her improvise a soundtrack to a Charlie Chaplin movie as it played.
