Their sound ‘plumbs the depths of sadness and scales the heights of ecstasy’ (Guardian) with strange, spine-tingling harmonies and heart-wrenching melodies drawn from traditional Bulgarian songs in contemporary arrangements. Formerly known as the Bulgarian State Radio & Television Female Vocal Choir, the group was created in Bulgaria by Philip Koutev, aka 'the father of Bulgarian concert folk music', but it was the 1986 release of Le Mystere Des Voix Bulgares Vol.1 on 4AD records that brought them to the attention of the wider world. 25 years later, this Grammy Award-winning ensemble have toured the globe to great acclaim, carving a distinctive voice within the rich heritage of Bulgaria's folk song, and return to tour the UK this autumn.
