Crikey, that's another month done... and two thirds of 2015!!! Came across this Bulgarian world music/modern chant group on one of my random trawls of the tubular. Lovely classical, madrigal-like rhythms combined with Sufi sounds and Bulgarian folk. I liked it - how about you?
(Castlefest is a Dutch annual gathering of Mediaeval/fantasy enthusiasts...at least that's what Wiki tells me.)
