I heard them last night on 9420 kHz, out in the glorious RF-pollution-free boonies, and enjoyed some of the most fantastically beautiful music I've ever heard. Signal was incredible, 555, I thought it must be a relay from the usual US suspects... Anyhow the music was varied, from haunting vocals to hammer dulcimer to strange stringed instruments. I couldn't place it, I kept thinking "Balkans"... which it is, sort of.
Introductions via shortwave to music you never imagined possible is an underrated joy of the hobby.
