This series features four top choirs from four different countries, each with its own unique choral tradition. The Irish choir Anúna specialises in old Celtic vocal traditions. From the United Kingdom comes the cream of the crop: The King’s Singers & VOCES8. Our country’s very own Cappella Amsterdam joins forces with Zero Dance Theatre. And representing Bulgaria is the legendary Le Mystère des Voix Bulgares, whose vocal technique and close harmony guarantee an unforgettable concert experience.
