Valentin Clastrier, the man who brought the hurdy-gurdy into the era of Varèse, Boulez & Xenakis, did a clever trick here: you bought the LP based on its serious-looking cover, expecting your "usual" #mediaeval or #tradfolk music and boom! you entered a very #contemporary world of unusual scales, made-up languages & African influences. The little deception was worth it: it definitely opened my ears to new soundscapes, & prepared me for the music of #2Othcentury composers.
