Found a radio station dedicated to this - a perfect find! No music is sadder and more energizing at the same time, giving bad fortune, giving history, the finger. Soulful not with vocal histrionics, which is interpretation, but with minor keys and changes in rhythm, soulful in the very bones of the musical structure.
Learned a few of these at the language school, later covered a number of songs on Bikel's brilliant album of the music. Man, tonight - in these times - the music sounds like the voice of the gods. As deep as Caruso.
