Demestvo presents "Lost Polyphonies", a program showcasing the earliest traditions of vocal polyphony from Europe, performed alongside contemporary compositions that engage with these chant traditions. The concert will feature music from Armenia, Georgia, Byzantium, France, Spain, England, Ukraine and Russia, including premieres of newly transcribed chants that have not been heard for over 300 years. Alongside these pieces, Demestvo and guest artists will perform new works by American composers Lucy McKnight and Caroline Shaw.
